Answer:
Step-by-step explanation:
let x,y be the sides of court.
2(x+y)=90
x+y=90/2=45
y=45-x
xy=500
x(45-x)=500
45x-x²=500
x²-45x+500=0
x²-25x-20x+500=0
x(x-25)-20(x-25)=0
(x-25)(x-20)=0
x=25,20
when x=25
y=45-x=45-25=20
when x=20
y=45-20=25
sides are 25 ft,20 ft.
Answer:
4
Step-by-step explanation:
because you subtract it.
Answer:
y=2x+7
Step-by-step explanation:
Equation of line: y = mx + b
where m is the slope, and b is the y-intercept
(x^3 - y^3)(x^3 + y^3)
You can get this by factoring based on the a^2 - b^2 model
