Answer:

There are 4 Phones in the Family phone Plan.

Step-by-step explanation:

Given:

Monthly payment for each phone = $\$22.91+\$20= \$42.91$

Let the number of phones in the plan be x

cost of the family data plan per month = $\$70$

Total Monthly bill = $\$241.64$

Total Monthly bill = Monthly payment for each phone $\times$ number of phones in the plan $+$ cost of the family data plan per month

∴ The equation becomes after substituting the value,

$(42.91 \times x) + 70 = 241.64\\42.91x=241.64-70\\42.91x=171.64\\x= \frac{171.64}{42.91}\\x=4$

∴There are 4 Phones in the Family phone Plan

(3/12) - (144/12) + (48/12)
-(93/12)

(ab+3)(ab−3)

=(ab+3)(ab+−3)

=(ab)(ab)+(ab)(−3)+(3)(ab)+(3)(−3)

=a^2b^2−3ab+3ab−9
