Use a compound angle formula to develop an equivalent expression for cos3x and use that expression to solve the equation 2cos3x+cos2x+1=0 on the interval 0x2.. Express your answer(s) as exact radians and approximate radians rounded to two decimals where applicable. Show your work. **HINT** express everything in terms of cosx.

$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)
