So first of all we need to know that area is length times width
Area = L x W
since we know the area is 42 and the length is 12 lets plug those in
42 = 12 x W
now we dont know what W is yet but we can figure it out by dividing 42 by 12
42/12 = 3.5
So W = 3.5!
but its asking for the perimeter and we know that perimeter is all of the sides of the rectangle added up. Heres a picture

3.5
see now we just add those all up together:)
12 + 12 + 3.5 + 3.5 = 31!!
so our perimeter is 31 inches:)
have a good one

Answer:
f(g(0)) = 45
Step-by-step explanation:
to evaluate f(g(0)) , evaluate g(0) then substitute the value obtained into f(x)
g(0) = - 3(0) - 3 = 0 - 3 = - 3 , then
f(- 3) = 2(- 3)² - 5(- 3) + 12
= 2(9) + 15 + 12
= 18 + 27
= 45
Hi, hope you’re having a good day!
Do you have the full picture? Please send if so.
Thanks! Have a great day! ❤️❤️
Answer:
- 108
Step-by-step explanation:
Substitute s = - 3 into the expression
- 3 | 15 - (- 3) | + 2(- 3)³
= - 3 | 15 + 3 | + 2(- 27)
= - 3 | 18 | - 54
= - 3 × 18 - 54
= - 54 - 54
= - 108
