Step-by-step explanation:
Base = 9x8=72
There are 2 triangles with a bottom edge of 9 and a slant height of 13:
1/2(9)(13)=58.5
There are 2 triangles with a bottom edge of 8 and a slant height of 11:
1/2(8)(11)=44
72+58.5+58.5+44+44=277cm²
Hi,
So we have g(x) = 4√(x). We're looking for g(45). Think of it like this: whatever number is in the place of x in g(x), just place that number AS x.
Therefore, we have :
g(45) = 4√(45) ⇒ (4) × (√(45)) ⇒ (4)(3√(5)) = 12√(5).
-Hope this helps!
