Answer:
The surface area increases by 4 times
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared
Let
z -----> the scale factor
x ----> the surface area of the new rectangular prism
y ---> the surface area of the original rectangular prism
so
we have
----> because is doubled
substitute and solve for x
----> surface area increases by 4 times.

Answer:
Hi there!
The answer to this question would be:
Step-by-step explanation:
the general equation would be: y= -1/2x + 17/2
first you want to solve for the slope (m): you wanna do delta y (change of y ) over delta x (change of x)
so it goes like (11-9)/(-5-(-1)) and you get -1/2
then you want to solve for the y intercept (b)
so you plug in one of the point that you were given, in this case I am using (-1,9)
so now the equation looks like 9 = 1/2 +b then solve for b and you get b=17/2
