Answer:
Step-by-step explanation:
The expression -9 + x*2 - 3x*2 + 4x has the following terms:
-9, x^2, -3x^2 and 4x. Please note: x^2 is correct if you meant "the square of x."
a) there is only one constant term; it is -9.
b) there are two terms involving x^2: x^2 and -3x^2. Combining them results in -2x^2.
c) there is only one term involving x: It is 4x.
d) -9 + x*2 - 3x*2 + 4x becomes -2x^2 + 4x - 9. Again, please use " ^ " to indicate exponentiation.

Answer:
357 minutes
Step-by-step explanation:
I subtracted 9 cents/minute from the 23 cents/minute to get 14 cents to get the difference between the two per minute charges. I then divided the monthly cost of $49.95 by .14 to get 356.79... So if you used 357 minutes in a month, the second plan would be 3 cents cheaper at $82.08 (.09 x 357= 32.13 + 49.95), vs. the first plan costing $82.11 (.23 x 357). At 356 minutes the first plan would still be cheaper.
A B D are all false and C is true
