Question

Please help me. i have no idea what to do

Answer 1

`-2+2√(7) and -2-2√(7)`

Explanation:

To find where x intersects x-axis, plug in y=0 and solve for x.

`(x+2)^2+(0-3)^2=37`

`(x+2)^2+(-3)^2=37`

`(x+2)^2+9=37`

`(x+2)^2=37-9`

`(x+2)^2=28`

`x+2=√(28)`

x+2=±2
`√(7)` Simplify square root

x=-2±2
`√(7)`

Answer 2

no idea either

but we are learning the same thing
