Answer:
x-coordinate is the first element in an ordered pair.
Each time the previous number is multiplied by 2
The shapes being similar means they are an even ratio to each other. the one on the left is 16/12 or 4/3 the one on the right.
this means you can say
and then solve for x.
(x-1)=4.5
x=5.5
Answer:
-4x+8
Step-by-step explanation:
x – 8 x + 7 x – 2 (x – 2)2
Multiply the numbers--- 2x2=4
x – 8 x + 7 x – 4 (x – 2)2
Expand -4(x-2): -4x+8
=x-8x+7x-4x+8
Add similar element
x-8x+2x-4x=-4x
-4x+8
