GIVING BRAINLIST SO PLZ PL PL HELP Shawn owns a lemonade stand and is trying to calculate his earnings. The problem is that his little brother keeps giving away cups of lemonade to his friends. Every time he does this, Shawn loses money. Each cup of lemonade costs Shawn $0.30 to make, and he sells them for $1.25 each. Last week, Shawn’s brother gave away 12 cups of lemonade.

PART A: Last week Shawn sold 26 cups of lemonade. What was his total profit based on how many cups he sold and his brother gave away?

A. $40.30

B. $13.40

C. $1.55

D. $0.95

PART B: How much profits did Shawn lose based on what his brother gave away?

A. $1.55

B. $11.40

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

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
