A triangle has sides measuring 7 centimeters and 13 centimeters that form an angle measuring 44º. Which of these is CLOSEST to the length of the third side of the triangle?
A)
8.1 centimeters
B)
8.7 centimeters
9.3 centimeters
D)
9.9 centimeters

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
