Higher Order Thinking A cell phone plan is shown at the

right. The rates, which include an unlimited data plan, are the

same each month for 7 months. The total cost for all 7 months

is $180.39. Let m represent the average number of minutes that

exceeds 700 minutes each month.

a. Write an equation to represent the given situation

b. Solve the equation to determine how many additional

minutes, on average, you use each month.

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
