Help please. Im stuck

Answer:16 square feet

Step-by-step explanation:

add the length of the top and the bottom face them multiply the sum of those two by the perpendicular height between them and the product is to be divided by 2 : ((a+b)h)/2)

Answer:

16 ft²

Step-by-step explanation:

First you'll find the area of the rectangle forming in the trapezoid:

3 x 4 = 12

Next, you'll think logically and understand that if BC is 3 feet, EF is also 3 feet. So, you'll subtract 5 - 3 = 2, so AE and FD is 1 foot.

So, you'll now multiply to find the area of the whole trapezoid:

4 x 1 = 4

So:

4 + 12 = 16

Answer:

144 degrees

Step-by-step explanation:

The exterior angles theorem states:

The exterior angles of a triangle = the sum of the interior angles that are NOT adjacent (touching) the exterior angles.

We can use this information to set up an equation:

x=48+96

x=144 degrees

Answer:

-6e^2 - 6ef + 11e + 11f

Step-by-step explanation:

FOIL

(-6e+11)(e-f)

-6e x e = -6e^2

-6e x f = -6ef

11 x e = 11e

11 x f = 11f

Answer:

1/4

or 25%

or 0.25

Step-by-step explanation:

With a question like this, you have to multiply.

1/2 * 1/2 = 1/4

or

0.5 * 0.5 = 0.25

Use this for formula

firstly

ax²+bx+c=0

and then

b±√(b²-4ac))/(2a)

1 . step

First compare the given equation with

general form

[tex]{a{x}^{2}\:+\:bx\:+\:c\:=\:0}[/tex]

2. step

Then find the value of discriminant

by the given equation below

[tex]\mapsto{{b}^{2}\:-\:4ac}[/tex]

3. step

subsitute the value of discriminant and other given value in Quadratic formula as per the equation .

[tex]{\rightarrow{\frac{-\:b\:±\:\sqrt{{b}^{2}\:-\:4ac}}{2a}}}\\[/tex]

Answer:

[tex](x^{2} +6x+8)-(x^{2} )[/tex]

Step-by-step explanation:

Area of Green including the white area:

[tex](x+4)(x+2)[/tex]

[tex]x^{2} +6x+8[/tex]

Area of White area is:

[tex]x^{2}[/tex]

Area of Green without white would be:

[tex](x^{2} +6x+8)-(x^{2} )[/tex]

Answer:

100 degrees

Step-by-step explanation:

Since triangle ABC is similar to triangle DEF, their angles are basically the same.

All angles of a triangle have to add up to 180.

We are already given two angles: 30 and 50

Add them together: 30 + 50 = 80

Now we subtract the number from 180

180 - 80 = 100

The remaining angle has to be 100 degrees

I made points on the lines of the graph at (-4, -4), (-2, -2), and (2, 2), which don't intersect so I believe the answer is D.

A) Yes, at a positive x-coordination or zero.

B) Yes, at a negative x-coordination or zero.

C) Yes, at negative and positive x-coordinates.

D) No, they will not intersect.

Answer:

See below.

Step-by-step explanation:

When there is a double negative, it converts the operation into an addition sign.

6--1 is actually 6+1, which is 7.

Answer:

y = 9x / 13

Step-by-step explanation:

Plug in x and y, example:

18 = 9(26) / 13

18 = 234 / 13

18 = 18

Answer:

{(0, 0), (1, 2), (2, 4), (3, 4)}

Step-by-step explanation:

A set of ordered pairs that represent a function is one in which each different ordered pair has a unique x-coordinate (so no two different ordered pairs can have the same x -coordinate).

Therefore, {(0, 0), (1, 2), (2, 4), (3, 4)} is a function as each different ordered pair has a unique x-coordinate.

The other sets all have different ordered pairs that share the same x-coordinate and so these sets do not represent functions.

The vertical line test is also used to determine whether a graph represents a function. If the vertical line intersects the graph only once, then the curve represents a function.  This test can be applied to ordered pairs, in that if two ordered pairs have the same x-coordinate but different y-coordinates, they will be on the same vertical line and therefore do not represent a function.

Answer:

The answer is 70 feet

Step-by-step explanation:

Here, We know the area so,

Area = Width × Height

Height = Area ÷ Width

H = 4200 ÷ 60 feet

H = 70 feet

Thus, The height of the billboard is 70 feet

Answer:

x=10

y = -9

Step-by-step explanation:

-8x - 10y = 10

3x + 2y = 12

Multiply the second equation by 5

5(3x + 2y) = 12*5

15x+10y = 60

Add this to the first equation to eliminate y

-8x - 10y = 10

15x+10y = 60

-----------------------

7x  + 0y  = 70

Divide by 7

7x/7 = 70/7

x = 10

Now find y

3x+2y = 12

3(10) +2y = 12

30 +2y =12

Subtract 30 from each side

2y = 12-30

2y = -18

Divide by 2

2y/2=-18/2

y = -9

Explanation:

Ignore the 15 pretzels. We're only focusing on the fish crackers.

3 orange + 5 yellow + 7 green = 15 total fish crackers

Of that total, 5 are yellow.

So approximately 5/15 = 1/3 = 0.333 = 33.3% of the crackers are yellow.

x + y = 15------(1)

x/y = 2------(2)

y = 15 - x

put this value in eq 2

x/(15-x) = 2

x = 2 (15 - x)

x = 30 - 2x

2x + x = 30

3x = 30

x = 10

y= 15 - x

y = 15 - 10

y = 5

Solution:

Given:

Let’s simplify the second equation to find out the value of x.

Now, let’s substitute the value of x into the first equation.

Now, let’s substitute the value of y into the simplified second equation.

Hence, the value of x and y are 5 and 10 respectively.
