Answer:
(a) 64/25
Step-by-step explanation:
The relevant properties of exponents are ...
a^0 = 1 . . . . a ≠ 0
(a^b)^c = a^(bc)
(ab)^c = (a^c)(b^c)
__
Your expression simplifies to ...

I think it would be 3x2 +2x -3
Given:
x² + 11x + 121 = x + 96
First, we need to convert it into a quadratic equation.
x² + 11x - x + 121 - 96 = 0
x² + 10x + 25 = 0
a = 1 ; b = 10 ; c = 25
Quadratic formula:
x = (-b <u>+</u> (√b² - 4ac)) ÷ 2a
The discriminant is under the radical sign
discriminant ⇒ b² - 4ac ⇒ 10² - 4(1)(25) ⇒ 100 - 100 = 0
Correct answer is A. 0
15x+40=115
15x+40-40=115-40
15x=75
15/15 x=75/15
x= 5
