I need help please with late math homework

Using the zero product property you can set each expression equal to 0 (or factor for some of them)
All you have to do is set them equal to zero and simplify to solve for x
a. (x+13)=0
x= -13
(x-7)=0
x=7
b. (2x+3)=0
x=-3/2
(3x-7)=0
x=7/3
c. x=0
(x-3)=0
x=3
d.
needs to be factored
factor out an x to get:
x(x-5) and set each equal to 0
x = 0
(x-5)=0
x=5
e.
also needs to be factored
(x-7)(x+5)=0
(x-7)=0 (x+5)=0
x=7 x=-5
f.
Also needs to be factored using the ac method:
(3x-1)=0
x=1/3
(x+5)=0
x=-5
I hope this helps! (if so, give brainliest please!!)

Answer:
The T-shirt lands in the bleachers at a height of 14 feet.
Step-by-step explanation:
The point where they meet is the solution of the simultaneous system of equations:
...........................................(1)
..............................................(2)
From (2),
.................................................(3)
Substituting (3) in (1),
Multiply through by 24 (the LCM of 3 and 8, the denominators of the fractions)
OR
OR
The value of <em>y</em> represents the height.
Substituting for <em>x</em> in (3)
We discard the negative answer.
Hence, the T-shirt lands in the bleachers at a height of 14 feet.
