The park district is paying to enlarge the area of a square-shaped dock at a local lake. the area of the dock will increase by 16 square feet. complete the equation below that can be used to find the area, x, of the original dock if the side length of the new dock is 20 feet. so, the square root of what equals(=) 20

The complete equation ⇒ The square root of ( x + 16 ) = 20

Step-by-step explanation:

Dock has a shape of square.

the side length of the new dock is 20 feet

So, The area of the new dock = 20 * 20

∴ The square root of (new area )= 20

∵ New area = original area + incremented area

∴ The square root of ( original area + incremented area) =20

But the area of the original dock = x

And, The area of the dock will increase by 16 square feet

∴ The square root of ( x + 16 ) = 20

where is the rest of the

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
