If pr = 4x – 2 and rs = 3x – 5, which expression represents ps?
x – 7
x – 3
7x – 7
7x + 3

PS = 7x-7

Step-by-step explanation:

Given the two expression

PR = 4x – 2 and RS = 3x – 5,

Adding the two vectors PR+RS = PS

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

Expanding the bracket will give;

PS = 4x-2+3x-5

Collecting the like terms

PS = 4x+3x-2-5

PS =7x-7

The expression that represent PS is 7x-7

sorry i just need to anwers this to get points

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
