9(-7b-6)
-63b-54
What I did was multiply 9 by -7b to gt -63b. Then, I multiplied 9 by -6 to get -54. :) hope this helps
The value is of this equation is -3.75
Step-by-step explanation:
circumference of a circle
U = 2 x pi x r
what you know:
U = 13
rearrange and solve for r
U/(2 x pi) = r
Substitute answers in, a = 3 and b = 2.
(3^2 - 2^2)/(3+2)
= (9-4)/5
= 5/5
= 1
