Answer:
20
Step-by-step explanation:
5 divided by 1/4
5 x 4
Area = 18x^2 + 69x + 60
Width = 3x + 4
Length = (18x^2 + 69x + 60) ÷ (3x + 4)
Length = 3(3x + 4)(2x + 5) ÷ (3x + 4)
Length = 3(2x+5)
Just type it into the graphing calculator, but reorder and solve for y first.
x + y = 9
y = 9 - x
y = x^2
In the graphing calculator,
Y1 = 9 - x,
Y2 = x^2
If you don't have a graphing calculator try desmos.
paint is needed to cover an entire wall : 2
if 1/2 gallon of paint cover 1/4 of a wall => 1 wall = (1/2)/(1/4) =2
