For those who may still need it in the future, the correct answer is actually: D: 3(x^2 + 1) +2
13,because it’s the single number that divides with 52
52:13=4
the answer is x= 10.
the steps would go like this.
4 + 3/5 × (15 + 2x) = 25
4 + 9 + 6/5x = 25
13 + 6/5x = 25
65 + 6x = 125
6x = 125 -65
6x = 60
x = 10
hope this helps
