(4x-2)+(3x-5)=PS
4x-2+3x-5=PS
4x+3x-2-5 (just rearranging)
=7x-7
Answer: 7x-7 ( third choice)
Answer:
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
