Question

If PR = 4x – 2 and RS = 3x – 5, which expression represents PS?

Answer 1

`7x-7`

Explanation:

We have been given that
`PR=4x-2` and
`RS=3x-5`. We are asked to find the expression that represents length of PS.

We know that
`PS=PR+RS`.

Upon substituting our given values in above equation, we will get:

`PS=4x-2+(3x-5)`

`PS=4x-2+3x-5`

`PS=4x+3x-2-5`

`PS=7x-7`

Therefore, the expression
`7x-7` represents length of PS.
