Solve 2x^2 + 6x = 36 by graphing the related function.

3 or -6

Step-by-step explanation:

2x2+6x=36

Collect like terms

2x2+6x-36=0

Divide all by 2

X2+3x-18=0

Factorise

Factors of -18 that will give +3 is +6&-3

X2+6x-3x-18=0

X(x+6)-3(x+6)=0

(X-3)(x+6)=0

X-3=0

X=3

X+6=0

X= -6

X= 3 or -6

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.
