Question

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

Answer 1

Answer:

$7x-7$

Step-by-step 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.
