The perimeter is D because you have to add all the sides up. 2 + 2 and 3 plus 3 equals 10x and then 8 + 8 and 2 + 2 equals 20 so 10x- 20.
Answer:
a = 3
Step-by-step explanation:
First start writing out the binomial expansion of 
![[1^7] + [7C1 * 1^6 *(ax)] + [7C2*1^5*(ax)^2]+[7C3*1^4*(ax)^3]](https://tex.z-dn.net/?f=%5B1%5E7%5D%20%2B%20%5B7C1%20%2A%201%5E6%20%2A%28ax%29%5D%20%2B%20%5B7C2%2A1%5E5%2A%28ax%29%5E2%5D%2B%5B7C3%2A1%5E4%2A%28ax%29%5E3%5D)
as you can see from this, the last bracket will produce our
term

Answer:
Enlargement
k =
=
Step-by-step explanation:
k =
If k > 1 then its an enlargement.
If k < 1 then its a reduction
Answer:
Step-by-step explanation:
(1,2) ; (3,2)
slope = y₂ - y₁ / x₂ - x₁
= ( 2-2 )/( 3 - 1) = 0
So, the line is parallel to x-axis and its slope is 0
F(b)-F(a)/b-a
A=10 B= -2
F(a) =4 F(b)=17
17-4/-2-10
13/-12
