How to use the zero product property and factoring solve for X

Mathematics

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. x^{2} -5x=0
 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. x^{2} -2x-35=0
 also needs to be factored
(x-7)(x+5)=0
(x-7)=0       (x+5)=0
x=7   x=-5

f. 3x^{2} +14x-5=0
Also needs to be factored using the ac method:
3 x^{2} +15x-x-5
3 x^{2} (x+5)-1(x+5)
(3x-1)(x+5)=0

(3x-1)=0
x=1/3
(x+5)=0
x=-5

I hope this helps! (if so, give brainliest please!!)

Choose the equations that are not linear equations. -x - y = 2 x 2 + y = 4 - y 3 = 1 x = 5
NeX [460]
X² + y = 4 and -y³ = 1x -5 are not linear equation because they contain a variable with a exponents. These types of equation are called quadratic equations.

PLEASE HELP!!!! IM SOO CONFUSED
dangina [55]

Answer:

4. 480.38m² 6. 3.35

Step-by-step explanation:

Assuming you're looking for the area of the shaded region, you must first be aware that the entire circle has a 360 angle.

From there. for no. 4:

You subtract 87 from 360 to find the angle of the major arc.

360-87=273

From there you must also know the formula to find the area of a sector which is:

(x/360)×pi×r²

In our case 273 is x and 14.2 is r so

(273/360)×pi×14.2²= 480.38

Do the same steps to find 6
