D. X=-2+sqrt(3) or -2-sqrt(3)
Please and Thank you!

D. X=-2+sqrt(3) or -2-sqrt(3)

Step-by-step explanation:

Quadratic Equation given:

In order to get rid of the fractions, multiply both sides by 4.

We get:

Completing the square:

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
