Answer:
9
Step-by-step explanation:
First add 6 to Benjamin's age to make it 18, which is twice Lucas's age. Because it's twice as much, divide 18 by 2 to get 9.
y +2 = 2(x + 2)

Step-by-step explanation:
choose the more precise measurement from the pair 54.1 cm and 54.16 cm.
Answer:
a
Step-by-step explanation:
Precision means that a measurement using a particular tool or implement produces similar results every single time it is used. For example, if you step on a scale five times in a row, a precise scale would give you the same weight each time. In math and science, calculating precision is essential to determine if your tools and measurements work well enough to get good data. You can report precision of any data set using the range of values, the average deviation, or the standard deviation.

Solve for v.
-8v+3(v-3) = 16
Hi there! :)
Answer:
[tex]\huge\boxed{v = -5}[/tex]
-8v + 3(v - 3) = 16
Distribute the 3:
-8v + 3(v) + 3(-3) = 16
-8v + 3v - 9 = 16
Combine like terms and simplify:
-5v - 9 = 16
-5v - 9 + 9 = 16 + 9
-5v = 25
Divide both sides by -5:
-5v/(-5) = 25/(-5)
v = -5.

Express 10 miles in kilometers.
Please help me choose if they are a yes or no.
Answer:
A)yes
B)yes
c)no
d)yes
e)yes
f)no
Part A
Answer: YesThis is the same as saying 2(AB+BC). A more written out version is AB+BC+CD+DA, though it's not needed since the opposite sides are congruent (AB = CD and BC = DA)
====================================================
Part B
Answer: YesThe diagonals of any parallelogram bisect each other. They cut each other in half.
====================================================
Part C
Answer: NoThe adjacent sides of a parallelogram aren't always equal in length. It only happens when we have a rhombus.
====================================================
Part D
Answer: YesThe angles mentioned are alternate interior angles. They are congruent due to AD and BC being parallel.
====================================================
Part E
Answer: YesWe can use the SSS or SAS congruence theorem to prove these triangles are congruent.
====================================================
Part F
Answer: NoThese are adjacent angles that aren't always the same measure. Diagonal AC does not bisect angle DAB. This only happens if we had a rhombus.
The areas of three circles are shown.

A = 27.5 cm
Not drawn to scale
Which list shows the circles in order from greatest area to least area?
A. Circle Z, circle Y, circle X
B. Circle Y, circle Z, circle X
C. Circle X, circle Z, circle Y
D. Circle X, circle Y, circle z
Answer:
C. Circle X, circle Z, circle Y
Step-by-step explanation:
Given
Circles X, Y and Z
Required
Order from greatest to highest
First, we need to simplify the given areas;
For Circle X
[tex]A = 9\pi[/tex]
Take [tex]\pi[/tex] as 3.14
[tex]A = 9 * 3.14[/tex]
[tex]A = 28.26[/tex]
For Circle Y
[tex]A = \frac{\sqrt3}{2}[/tex]
This gives
[tex]A = \frac{1.732}{2}[/tex]
[tex]A = 0.866[/tex]
For Circle Z
[tex]A = 27.5[/tex]
By comparing the above areas;
X has the largest area; followed by Z and then Y
Hence,
option C answers the question

if c(x) = 4x - 2 and d(x)= x2 + 5x, what is (c.d)(x)?
Answer:
4x^3 + 18x^2 - 10x.
Step-by-step explanation:
(c.d)(x) = (4x - 2)(x^2 + 5x)
= 4x^3 + 20x^2 - 2x^2 - 10x
= 4x^3 + 18x^2 - 10x.
4x+10y=70 in slope-intercept form

Three boys were running around the track. The first can run 1 lap in 15 min. The second can run 1 lap in 25 min. and the third can run a lap in 10 min. If the boys start running at 12:45, what time will all 3 boys pass each other again?
Answer:
At 15:15
Step-by-step explanation:
Given,
the 1st boy can run a lap in 15 minutes
the 2nd boy can run a lap in 25 minutes
the 3rd boy can run a lap in 10 minutes
Now if they start running at 12:45,they will meet after the time which will be equal to the L.C.M. of their time need to run a lap.
[tex]L.C.M.[/tex] of 15,25 & 10 = 150
So,they will pass each other after 150 minutes or 2 hours & 30 minutes.
If we add it with 12:45 we'll get 15:15 or 3:15 pm

which of the following statements does not represent the same value as the others
the absolute value of negative 9
the absolute value of 9
the distance between 0 and -9
the opposite of 9
Answer:
the opposite of 9
Step-by-step explanation:
the absolute value of nagative 9, is positive 9.
the absolute value of postive 9, is postive 9.
the distance between 0 and nagative 9 on a line would be a count of postive 9.
the opposite of postive 9 is negative 9 (the only one with a diffrent outcome)

Answer:
a=2√2+4b = 3Step-by-step explanation:
√24 = 2√6
√48 = 4√3
Then the sum is ...
√24 +√48 = 2√6 +4√3
Factoring out √3, we have ...
= (2√2 +4)√3
Matching this to the form a√b, we have
(2√2+4)√3 ⇒ a=2√2+4, b = 3

Is 4 to 7 the same as 7 to 4? explain why or why not
Answer:
Just say, "No, 7 to 4 is not the same as 4 to 7. I don't know why, but I just know because you taught me it wasn't."
Step-by-step explanation:
It worked for me lol
Answer:
4 to 7 is pretty much 4 divided by 7 which = 4/7 and 7/4 is 1 3/4. which is obviously greater. So they both equal different answers.

HELP MEE PLZZZZ I DON'T UNDERSTAND THIS
Answer: Choice D. [tex]6.44 \times 10^{-4}[/tex]
========================================================
Work Shown:
We multiply the coefficients 9.2 and 7 to get 64.4, which is the same as 6.44*10^1 in scientific notation. When multiplying exponential expressions with the same base, we add the exponents
This is what the steps could look like
[tex]\left(9.2 \times 10^{-9}\right)\times\left(7 \times 10^{4}\right)\\\\\left(9.2\times7\right)\times\left(10^{-9} \times 10^{4}\right)\\\\\left(64.4\right)\times\left(10^{-9+4}\right)\\\\\left(6.44\times 10^{1}\right)\times\left(10^{-5}\right)\\\\6.44\times\left(10^{1}\times 10^{-5}\right)\\\\6.44\times\left(10^{1+(-5)}\right)\\\\6.44\times 10^{-4}\\\\[/tex]
The final result is in scientific notation as the coefficient c is restricted such that [tex]0 \le c < 10[/tex]
