Question

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

Answer 1

For this case we have that the PS segment is given by the sum of the PR and RS segments. That is to say:

$PS = PR + RS$

Where:

$PR = 4x-2\\RS = 3x-5$

Adding we have:

$PS = 4x-2 + (3x-5)\\PS = 4x-2 + 3x-5\\PS = 4x + 3x-2-5$

The same signs add up and the same sign is placed.

$PS = 7x-7$

Answer:

$PS = 7x-7$

Option C

Answer 2

Answer:

ps = ps + rs

PR = 4x – 2

RS = 3x – 5

7x - 7
