Please help me with this

x + 4

Step-by-step explanation:

Area = Width * Length

x^2 + 13x + 36 = Width * (x + 9)

Width = (x^2 + 13x + 36) / (x+ 9)

Width = x + 4

Hope this helps)))

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
