Well I believe the answer is A. instead of B,C, or D,
This is because you would not need to multiply right away. The problem addresses that John buys 5 more which means to add and if you needed to multiply right away it would have said twice as much or greater to for an increasive value.
Solution: 2×45+5=f
A. You are told that the length equals (x + 15), which means that you must factorise the area in order to find the width:
45 ÷ 15 = 3
(x + 15)(x + 3)
So the width is x + 3
b. Now you substitute in the value of x into both brackets, so
length: (x + 15) = (8 + 15) = 23 yards
width: (x + 3) = (8 + 3) = 11 yards
I hope this helps!
This is the answer, hope you understand
It is linear... x is increasing by 2 and y is increasing by 7 each time
