Answer:4,67
Step-by-step explanation:
Answer:
1 1
------ + -------
r^7 s^12
Step-by-step explanation:
r^(-7) + s^(-12) can be re-written as
1 1
------ + ------- by putting to use the rule:
r^7 s^12
1
x^(-a) = ----------
x^a
A = π*r^2
r = √(A/π) = √(45/π) ≈ 3.78
The radius is approximately 4 inches.
Subtract x on both sides the result you divide it by 5
I'm not 100% sure but my best guess would be a rectangle. ( do not give brainliest if wrong, i wanna make sure its right)
