The answer is $70 so D
Because $59.5 is 85% of the original price, use 59.5/0.85 to find the original price
The answer is C. 7 x ( 2 x 2 )
The answer and equation is 17 - 19 = -2
Answer:
• x = -4, x = 0, x = 1
Step-by-step explanation:
x is a factor of all terms, so x=0 is a zero. (Eliminates choices 1 and 5.)
The sum of coefficients is 0, so x=1 is a zero. (Eliminates choices 3 and 4.)
Reversing the sign of the odd-degree terms gives signs of -++, so there is one sign change, hence one negative real root (by Descartes' rule of signs). This confirms choice 2 as the answer.

Of course, your graphing calculator can answer this almost as quickly.
