The answer is C)
Step-by-step explanation:
4x(x+1) - (3x-8)(x+4)
(4x^2+4x) - (3x^2+12x-8x-32)
(4x^2+4x - 3x^2-12x+8x+32)
4x^2-3x^2+4x+8x-12x+32
=x^2+32
Quadratic binomial
The range is the highest number minus the lowest number
98 - 13 = 85 <==
Answer:
r = 15
Step-by-step explanation:
10(8r + 23) = 1430
Divide both sides by 10.
8r + 23 = 143
Subtract 23 from both sides.
8r = 120
Divide both sides by 8.
r = 15
(a^2)^4 = a^8, and (b^3)^4 = b^12. Thus, the quotient is
a^8
--------
b^12
