Kenji earned $40 mowing lawns last week. he wants to us his money to buy 4 videos that cost $9.99, $12.95, $6.75, and $10.39. does he have enough money to purchase the videos?

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

lockers 1, 4, 9, 16, 25, 40, and 49 are open
