Answer:
f = 2 + -15x-1 + x
Step-by-step explanation:
Simplifying
f(x) = x2 + 2x + -15
Multiply f (x)
fx = x2 + 2x + -15
Reorder the terms:
fx = -15 + 2x + x2
Solving
fx = -15 + 2x + x2
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = -15x-1 + 2 + x
Simplifying
f = -15x-1 + 2 + x
Reorder the terms:
f = 2 + -15x-1 + x
The answer is 3 (or 3.08)
Answer
(C) 
Explanation:
Congruence of these two angles directly implies p||q.
A=πr^2
A=3.14(11^2)
A=3.14(121)
A=379.94 which is simplfied to 380
Answer:
$807.5
Step-by-step explanation:
