the answer is trueeeeeeeee
Answer:
The new surface area will be
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
In this problem
The scale factor is
so
Multiply the scale factor squared by the original surface area to obtain the new surface area
So I’ll do question 3. So normally you see f(x)= something plus x (something like that) you see it as a function of x.
So that notation of f(-1) means the function of -1. Which means you need to sub in -1 for x.
f(x)=-5x+5
f(-1)=-5(-1)+5
Negative times a negative is a positive
f(-1)=5+5
f(-1)=10
Answer:
10
Step-by-step explanation:
4 x 10 = 40
40 + 12 = 52
