Answer:
20 units
Step-by-step explanation:
The perimeter of a rectangle is
P = 2(l+w)
P = 2( 3x+2 + 4x)
Adding like terms
P = 2( 7x+2)
We know the perimeter is 74 units
74 = 2 ( 7x+2)
Divide by 2
74/2 = 2/2 (7x+2)
37 = 7x+2
Subtract 2 from each side
37-2 = 7x+2-2
35 = 7x
Divide by 7
35/7 = 7x/7
5 =x
We want to find the length RS = PQ = 4x
RS = 4x = 4*5 = 20

Given:

Taking the LCM as 6,

Applying the product rule to
:-

Now applying the product rule to 1/6:-

Hence, the answer.
You can take out 2x from both sets making 4x+5 since there is no other number or variable than can simplify the sets equally the GCF is 2x
So f(x) + g(x) = -5x -4 +6x -7 = x -11 so choice B. is right sure
hope this will help you
