Answer:
<h2>Yes. It's a right triangle.</h2>
Step-by-step explanation:
If a ≤ b < c are the length of the sides of a right triangle, then
a² + b² = c².
We have:
a =30 ft, b = 40 ft and c = 50 ft.
Check the equality:
L = 30² + 40² = 900 + 1600 = 2500
R = 50² = 2500
L = R
Answer:
F = -79.78
Step-by-step explanation:
You need to set F by itself
5/9(F-32) = -62.1
multiply the reciprocal of 5/9 on both sides to eliminate 5/9. The reciprocal is 9/5
-62.1 times 9/5
= -111.78
F-32 = -111.78
add 32 on both sides to get F by itself.
-111.78 + 32 = -79.78
Your final answer
Answer:
f (x)=11
Step-by-step explanation:
f (x)= x + 8
f (3)= (3 +8)
=f(x) =11
**replace the x with a variable which is 3
