So if you want it to be 9 less than your number (x) then you would subtract nine.
So it would be:
x - 9.
So if your "number" is 12 then you would substitute x for 12 and it would be 12-9. The answer is 3. So 3 is 9 less than a number (12).
I believe
Y=3x+6
y=mx+b 3 is slope and m is also the slope, six is b because it’s where it BEgins :)

Answer:
D
Step-by-step explanation:
Height: h
Length: 2h + 15
Area = length × width
4h² + 42h + 90
2(2h² + 21h + 45)
2[2h² + 15h + 6h + 45]
2[h(2h + 15) + 3(2h + 15)]
2(h + 3)(2h + 15)
Width = 2(h+3) = 2h + 6
Length: 2h + 15
Difference:
(2h + 15) - (2h + 6)
2h + 15 - 2h - 6
9
Width is 9 feet shorter than the length
