Answer:
Step-by-step explanation:
2x²+7x=-3
2x²+7x+3=0
2x²+x+6x+3=0
x(2x+1)+3(2x+1)=0
(2x+1)(x+3)=0
x=-1/2,-3
so C
Answer:
12x⁶+24x⁵-180x⁴/ 30x³+240x²+450x
Step-by-step explanation:
(x-3)(x+5)=x²+2x-15
12x⁴(x²+2x-15)= 12x⁶+24x⁵-180x⁴
(x+3)(x+5)=x²+8x+15
30x(x²+8x+15)= 30x³+240x²+450x
Answer:
D. $67.50
Step-by-step explanation:
A ticket costs $5.25, a drink costs $2.00, and a popcorn costs 4.00. Each person in the group buys all of these. So we know that each person is paying:
