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:
How to show that they are equal.
Step-by-step explanation:
3/4 times 25 equals 75/100 and then when you turn it into a decimal it is 0.75. That is why they are equal.
13 ESSA É A RESPOSTA CORRETA DA SUA PERGUNTA.
So percent means parts out of 100 so 17%=17/100
400 marbles
17% of 400=blue
'of' can be translated to multiply
17%=17/100
17/100 ties 400=6800/100=68
he has 68 blue marbles
