=(4-x^2)(a+b)
=(2^2-x^2)(a+b)
=(x+2)(x-2)(a+b)
I think it hopefull to you
Answer:
5 months
Step-by-step explanation:
Set up an inequality, using x to represent months.
(The 35 and 40 represent the cost per month, and you add the 100 and 75 just once because it's a one-time fee and not monthly)
35x + 100 < 40x + 75
Now solve for x.
5x > 25
x > 5
This means that the membership will be less expensive after 5 months.
7(x + 1) = 21
7x + 7 = 21
7x = 14
x = 2
1/4q = 3w + 3...multiply both sides by 4
q = 4(3w + 3)
q = 12w + 12 <===
