Answer: 4x^2 + 6xy + 2y^2
Step-by-step explanation:
(2x + y)(2x + 2y) =
2x*2x + 2x*2y + y*2x + y^2y =
4x^2 + 4xy + 2xy + 2y^2 =
4x^2 + 6xy + 2y^2
Answer:
4x² + 6xy + 2y²
Step-by-step explanation:
Given
(2x + y)(2x + 2y)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(2x + 2y) + y(2x + 2y) ← distribute both parenthesis
= 4x² + 4xy + 2xy + 2y² ← collect like terms
= 4x² + 6xy + 2y²
point B is the image of the point A when A is rotated 90° counterclockwise around the origin
point B must be the same ________ from the origin as point A
Answer:
distance
Step-by-step explanation:
Point B must be the same distance from the origin as point A.
What is Rotation?Rotation is a kind of geometric transformation where a figure or point is rotated by a certain degrees about a given point.
Given that,
Point B is the image of the point A when A is rotated 90° counterclockwise around the origin.
A point P(x, y) after the rotation of 90°counterclockwise around the origin is P'(-y, x).
So the x coordinate changes to the negative of y coordinate and y coordinate changes to x coordinate.
Distance between P(x, y) from origin (0, 0) is √(x² + y²)
Similarly the distance P'(-y, x) from origin (0, 0) is √((-y)² + x²) = √(x² + y²)
Hence they are at the same distance.

Solve for t. You must write your answer in fully simplified form.
−19=7t
Answer:
t=-19/7
Step-by-step explanation:
you need to isolate for t which means you need to get t all alone on one side of the equation. Do do that you can divide both sides by 7. This gives you -19/7=7t/7
we know that anything divided by itself is 1 so we get -19/7=t
This is the simplest for because 19 and 7 are both prime numbers, so you can't simplify them.

Find the degree measure of each angle in the triangle. Giving brainly
Answer:
∠ I = 39°, ∠ J = 51°, ∠ K = 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the3 angles and equate to 180
3x + 21 + 5x + 21 + 90 = 180, that is
8x + 132 = 180 ( subtract 132 from both sides )
8x = 48 ( divide both sides by 8 )
x = 6
Then
∠ I = 3x + 21 = 3(6) + 21 = 18 + 21 = 39°
∠ J = 5x + 21 = 5(6) + 21 = 30 + 21 = 51°
∠ K = 90°

The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wraps cost $1.00 and the chicken wraps cost $1.50. Today they made $149.00 from the 105 wraps sold. How many wraps sold were vegetarian?
Answer:
17 wraps
Step-by-step explanation:
Given data
let the number of vegetarian wraps be x
and chicken wraps be y
so
x+1.5y= 149------------1
and
x+y= 105----------------2
the systems of equation for the problem is
x+1.5y= 149
x+y= 105
from 2
x= 105-y
put this in 1
105-y+1.5y= 149
105-0.5y= 149
-0.5y= 149-105
-0.5y=44
y= 44/0.5
y= 88
put y = 88 in 2
x+88= 105
x= 105-88
x= 17

Using this equation, what would we have expected to be the value of his condo in the year 2006?
Value in 2006:
Answer:
The value in 2006 is 366,025
Step-by-step explanation:
Here, we want to get the value of y in 2006
what we have to do here is to find and substitute the missing value of x
The missing value x is the difference between the number of years in 2002 and 2006
we have this as 2006-2002 = 4
so we have to substitute 4 here for x
Thus, we have this as;
y = 250,000(1.1)^4
y = 366,025

what is the volume of the rectangular pyramid shown
Answer:
80 cm^3 = V
Step-by-step explanation:
The volume of a rectangular pyramid of base area A and height h is
V = (1/3)(base)(height).
Given that the dimensions of the base are L = 10 cm and W = 4 cm, the base area is 40 cm^2.
The height of the pyramid is h = 6 cm.
Therefore the volume of this particular pyramid is
V = (1/3)(40 cm^2)(6 cm), or V = 80 cm^3

Amber trains for 1h one day. She runs for 10 min, walks for 5 min, runs for 15 min, and walks for 5 min. Her running time increases by 5 min each interval, but she always walks for 5 min. Use fractions of one hour. Write an addition equation that represents Amber's total running time. Find her total running time.
Answer:
Part A
The addition equation that gives Amber's total running time is presented as follows;
Amber's total running time = 1/6 hr + (1/6 + 1/12) hr + 5/12 hr
Part B
Amber's total running time = 5/6 hr = 50 minutes
Step-by-step explanation:
Part A
The given parameters are;
The time duration Amber first ran = 10 min = 1/6 hr
The time duration Amber walks in between = 5 min = 1/12 hr
The increase in the number of minutes Amber runs in subsequent times = 5 min = 1/12 hr
Therefore, the Amber's total time is given as follows;
1/6 hr + 1/12 hr + (1/6 + 1/12) hr + 1/12 hr + x hr = 1 hr
7/12 hr + x hr = 1 hr
x hr = 1 hr - 7/12 hr = 5/12 hr
x = 5/12
Therefore, her total running time is given by the following addition equation;
Amber's total running time = 1/6 hr + (1/6 + 1/12) hr + 5/12 hr
Part B
Therefore her total running time is given as follows;
Amber's total running time = 1/6 hr + (1/6 + 1/12) hr + 5/12 hr = 5/6 hr = 50 minutes

Find the area and the circumference of a circle with diameter of 5m. Use the value 3.14 for π, and do not round your answers. Be sure to include the correct units in your answers
Answer:
Step-by-step explanation:
Diameter (d) = 5cm
Radius ( r) = d/2 = 5 / 2 = 2.5
Now
Area
= πr²
= 3.14 * (2.5)²
= 19.625 m²
Circumference
= πd
= 3.14 * 5
= 15.7 m

A triangle has a 62° angle and a right angle. What is the measure of the third angle?
Answer:
Measure of the third angle is 28°
Step-by-step explanation:
A Triangle has three angles in total which when summed up equal to 180 degrees. Now the information in the question is that the first angle is 62° the second angle is a right angle which means it is a 90° angle and we need the third angle, and when all of this when added equals 180° So,
We let the third angle be called x.
[tex]62 + 90 + x = 180\\\\152+x=180\\\\x=180-152\\\\x=28[/tex]
So our third angle is 28°
Step-by-step explanation:
Sum of angles on a straight line = 180°
Let the third angle be x°
62° + 90° + x° = 180°......(Sum of angles on a straight)
152° + x. = 180°
x°. = 180°-152°
x° =28°

Answer:
it should be 15
Step-by-step explanation:
Answer:
15 units
Step-by-step explanation:
Since the x- coordinates of both points are the same, then calculate the distance between the y- coordinates using the absolute value, that is
d = | - 8 - 7 | = | - 15 | = 15 , or
d = | 7 - (- 8) | = | 7 + 8 | = | 15 | = 15

1. What is the mass of an object if it takes a net force of 25 N to accelerate it at a rate of 0.88 m/s2?
Answer:
28.4 kg
Step-by-step explanation:
F = ma
F is 25 N and a is 0.88 m/s^2
25 = 0.88m
Divide both sides by 0.88
m = 28.4 kg
The mass of an object is 28.4 kg.
It is required to find the mass of an object.
What is force?The capacity to do work or cause physical change; energy, strength, or active power. The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction.
Given:
Net force = 25 N
Acceleration=0.88 m/s^2
According to given question we have,
F = ma
25 = 0.88m
Divide both sides by 0.88
m = 28.4 kg
Therefore, the mass of an object is 28.4 kg.
