C
the square of the sum of 7 times x and 3 is expressed as
7x + 3 ← the sum of 7 times x and 3
(7x + 3)² ← the square of the sum of 7 times x and 3
4 times the difference of x and 1 is expressed as
x- 1 ← the difference of x and 1
4(x - 1) ← 4 times the difference of x and 1
putting it all together gives
(7x + 3 )² / 4(x - 1 ) → C

im sorry but is it a option choice?
if so its the answers are b b d a
sorry if i did not help.
So when adding fractions you need the same denominator so I chose to make 2/10 into the 100 denominator so you multiply 2/10 by 10/10 and you get 20/100 so you then add 45/100 + 20/100 and you get 65/100
