Question

Isosceles 7 X + 3 5x + 7

Answer 1

Hey there!

If your problem looks like:
`(7x`
`+3)`
`(5x`
`+7)`

You have to
`distribute` the equation, so

`7x`
`(5x)`
`+`
`7x`
`(7)`
`+`
`3`
`(5x)`
`+`
`3(7)`

`Simplify` the
`equation` out

`7x`
`(5x)`
`=`
`35x^2`

`7x`
`(7)`
`=`
`49x`

`3`
`(5x)`
`=`
`15x`

`3(7)`
`= 21`

`Combine` your
`like`
`terms`

`49x`
`+`
`15x`
`=`
`64x`

Therefore your
`\boxed{answer}` is:

`35x^2`
`+`
`64x`
`+`
`21`

Good luck on your assignment and enjoy your day!
