Answer:

Step-by-step explanation:
Let's factor the numerator and denominator first.
x^2+5x-6 is a quadratic in the form of x^2+bx+c.
If you have a quadratic in the form of x^2+bx+c, all you have to do to factor is think of two numbers that multiply to be c and add to be b.
In this case multiplies to be -6 and adds to be 5.
Those numbers are 6 and -1 since -1(6)=-6 and -1+6=5.
So the factored form of x^2+5x-6 is (x-1)(x+6).
x^2+9x+18 is a quadratic in the form of x^2+bx+c as well.
So we need to find two numbers that multiply to be 18 and add to be 9.
These numbers are 6 and 3 since 6(3)=18 and 6+3=9.
So the factored form of x^2+9x+18 is (x+3)(x+6).
So we have that:

We can simplify this as long as x is not -6 as

I obtained the last line there by canceling out the common factor on top and bottom.
The volume of the pyramid is 40
.
Explanation
The volume of the pyramid is determined by its base area and the height.
Given that
The base of the pyramid given in the problem is a rectangle
length of the base= 5 cm
breadth of the base=4 cm
base area A= length*breadth(area of rectangle)
=4*5=20 
height of the pyramid h=6 cm
volume of the pyramid=1/3 Ah
=1/3 *20*6=40
T=number of shirts
T=total cost (shirts + shorts)
12t+5(10)=T
12t+50=T
