How i would solve it is
1. 72.6-35=37.6
2. 37.6/.05=752
and for April you can do the same process phone bill - 35 for usage then divide the answer by .05

After rounding off, Answer is 6.
Hope this helps. - M
Answer:
1. (x+5)(x-1)
6. (3x+4)(x-6)
9. (x+5)(x-5)
Step-by-step explanation:
To factor an equation, break the polynomial into two binomials which multiply to make it. There are three main ways to factor:
Regular: Find two numbers that multiply to C and add to B from
.

Grouping: Find two numbers that multiply to A*C and add to B. Then split B into the two factors and factor by GCF.

Difference of Squares: Factor by taking the square root of each term.
