4 -27 167 -996
4x^2 - 27x + 167 remainder - 996
Answer is 1.6 hours
T=D/S
_=86.4/54
1.6=86.4/54
(Hopes this helps)
Yes, there was a mistake in applying the distributive property. If you have to perform
you have to multiply both terms in the parenthesis by 3, not just the first one.
So, the correct expansion would be
Answer:
x^2 - 6x + 147 so the coefficient is 1
Step-by-step explanation:
First, simplify the equation.
1. 2/3x(2x-3) = (2x/3)(2x-3)-(x-7)(x+7)
2. 2x-3(2x/3) = (2x(2x-3)) - (x-7)(x+7)
3. Expand -(x-7)(x+7) = -x^2+49
Combine to get (x^2 - 6x)/3 +49
Simplify to get x^2 - 6x + 147. The coefficient of the quadratic term is one.
