Answer:
5.7in
Step-by-step explanation:
using Pythagorean theorem
c^2=a^2+b^2
c=9in ,a=7in,b=xin
9^2=7^2+x^2
81=49+x^2
x^2=81-49
x^2=32
x=√32
x=5.7in(to the nearest tenth)
We need to rearrange this to solve.
h-5 ≥ -16h-5 ≥ -16
Subtract -5 from all of it we get:
h ≥ -16h ≥ -11
Therefore none of the answers are correct.
3 + 3 + 3 + 3 + 5 + 5 = 22
the perimeter is 22 cm
I think its 9 because 9 times 2 is 18 9 times 6 is 54 and 9 times 8 is 72
