A cell phone plan costs $150 to start, Then, thero is a $50 charge each month. What is the total cost, y, for x months? Which equation match this situation Y=150-50x. Y=50x+150. Y=150x+50. -50x+150=y

Y = 50x + 150

Step-by-step explanation:

50 per month (x = unknown number of months) === 50x

$150 is the starting charge (automatic +150)

Y = total cost

Y = 50x + 150

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
