Mathematics

Multiply the equation (x-2y=10) by -1
-x+2y=-10
x+3y=5
The x’s cancel out
2y=-10
3y=5
Combine
5y=-5
Divide both sides by 5
y=-1
Plug in y to either original equation
x-2(-1)=10
x+2=10
Subtract 2 from both sides
x=8, y=-1

padilas [110]

Answer:

Option (3)

Step-by-step explanation:

Area of a circle is given by the formula,

Area = πr²

Here, r = radius of the circle

Since, radius of the circular trampoline = 8 feet

Area of the cover required for the circular trampoline = π(8)²

                                                                                         = 64π square feet

Therefore, Option (3) will be the answer.
