I believe it's 3 because 4 times 3 equals 12 and 12 plus 8 equals 20!
4(3)+8=20
Hoped this helped! :)
Where is the photo u forgot it
Answer:
h = 3V / πr^2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
X * y = -48
x + y = 8
y = -48/x
x -48/x = 8
x^2 - 48 = 8x
x^2 - 8x -48 = 0
x = 12
y = -4
The cost would be $582.40!
