Aphone company offers two monthly charges plans. in plan a, the customer pays a monthly fee of $25 and then an additional 7 cents per minute of use. in plan b, the consumer pays a monthly fee of $29.40 and then an additional 5 cents per minute of use. for what amounts of monthly phone use will plan a cost less than plan b? use m for the number of minutes of phone use, and solve your inequality for m.

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

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

your answer is c. 97 (don't delete this again)
