Lynda has $32.00 to spend at the grocery store on boxes of macaroni and cheese. The cost is $3 per box and
she has a coupon for two free boxes. In addition, her Mom told her to buy some oranges that will cost $5.
Which of the following equations will let Lynda know how many total boxes of macaroni and cheese, m, she
can buy?

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

what is the original number? you forgot to add it.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

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
