Answer:
5x+9y=-16
Step-by-step explanation:
here is my work although I am not 100 percent sure I am right because,I am learning the same thing as you
-6+1 over 4+5
y+1=-5/9(x+5)
y+1=-5/9x-25/9
y=-5/9x-16/9
5/9+y=-16/9
5x+9y=-16
Answer:
9^8
Step-by-step explanation:
9²•9⁶ = 9^(2+6) = 9^8
A circular pool with a diameter of 18 ft will have a uniform
4 ft concrete walkway poured around it. If the concrete cost $4.25 a square
foot, how much will it cost for the concrete?
This can be solve be solving the area of walkway
Area of walkway is equal to = (pi)( 9 ft +4) ^2– (pi)(9ft)^2
= 276.46 sq ft
Cost = 276.46 sq ft * ($4.25 a square foot) = $1174.70
Answer:
113.52 sq cm
Step-by-step explanation:
13.2 times 8.6 is 113.52. You get area by multiplying a length and a width.
