9 + 5x- 5 + 3x = 4+8x = 4(1+2x)
2x+9-x+3 = x+12
7x+5-2x+8 = 5x +13
combine like terms and add and subtract
hope this helps XD have a wonderful break
Is Y the box in the triangle ??If so the value of y would be 90
First you have to subtract 3x and then divide everything by -4 to get y=3/4x-7

Answer:factor of 9
Step-by-step explanation:
Given
prism were changed by a scale factor of 3
Suppose prism is rectangular in shape
So surface are is 
Where l=length
w=width
b=breadth
So new length,breadth and width is






So new surface area would change by a factor of 9
