A gym charges $10 per month for a membership and $3.00 for each cycling class . If Maria’s total bill for one month was $88.00 , how many classes did she take?

Step-by-step explanation:

She took 29 classes in total

26 classes

Step-by-step explanation:

first you do 88-10=78 then divide 78 by 3 which gives you 26

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

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
