(x^2+5x-36)/(x^2-16)
=(x^2+9x-4x-36)/(x^2-4^2)
=x(x+9)-4(x+9)/(x+4)(x-4)
=(x-4)(x+9)/(x+4)(x-4)
=x+9/x+4
Hope this helps.

Answer:
the one on the left (the first one)
Answer:
In number 1:
m = 10/3
b = 19
Step-by-step explanation:
To find the answers to these, simply look to the coefficient of x and the constant at the end of the equation. The number attached to x is always m (which is known as the slope). The number at the end is b (or the y-intercept).
We can subtract t from both sides to get...
x+t = 3.45
x+t-t = 3.45-t
x = 3.45-t
