I think you would do 39 x 4 because if the SQUARE brick has sides 1 foot long, you count up the sides and get 4 feet. She has 29 square feet of patio bricks so you would multiply 39 x 4. I don't know if this is correct. Hopefully I helped!
Answer:
14
Step-by-step explanation:
Answer: 3x-y=2 and 3x-y=1 (First Answer Choice)
First you want to isolate the y. (Subtraction Property of Equality)
-y = -3x+2 -y = -3x + 1
Then, extract the negative from the y by dividing by -1. (Division Property of Equality and Distribute)
(-1)-y = (-1)(-3x + 2) (-1)-y = (-1)(-3x + 1)
y = 3x - 2 y = 3x - 1
Notice that if you do the steps for the other answer choices, you would end up with a negative slope, which is not presented in the picture. A negative slope goes up down and positive slip goes down up.
Use Pythagorean Theorem
C2 = a2 + b2
c2 = 20^2 + 48^2
c2 = 400 + 2304
c2 = 2704
c = 52
