The zero product property tells us that if the product of two or more factors is zero, then each one of these factors CAN be zero.

For more context let's look at the first equation in the problem that we can apply this to: (x-3)(x+4)=0

Through zero property we know that the factor (x-3) can be equal to zero as well as (x+4). This is because, even if only one of them is zero, the product will immediately be zero.

The zero product property is best applied to factorable quadratic equations in this case.

Another factorable equation would be 2x^{2}+6x=0 since we can factor out 2x and end up with 2x(x+3)=0. Now we'll end up with two factors, 2x and (x+3), which we can apply the zero product property to.

The rest of the options are not factorable thus the zero product property won't apply to them.

2/5x -1=9. Complete each step of the solution and check your solution
kkurt [141]

Answer:

x = 25

Step-by-step explanation:

2/5x - 1 = 9

Add 1 to both sides

2/5x = 10

Multiply both sides by the reciprocal of 2/5, which would be 5/2

x = 25

Slope = (-2 + 4)/(-2-2) = 2/-4 = -1/2

y = mx + b
so
b = y - mx
b = -2 -(-1/2)(-2)
b = -2 - 1
b = - 3

equation
y = -1/2x - 3

answer is B.
y = -1/2x - 3

A rectangular swimming pool is 20 ft long 15 feet wide,and 6 feet deep. How much water is needed to fill the pool completely ?
sergejj [24]

Answer: 1,800 ft.³

Step-by-step explanation: To find out how much water is needed to fill the pool, we need to find the volume of the pool. It's also important to understand that the swimming pool is a rectangular prism so we are finding the volume of a rectangular prism.

To find the volume of the pool, we use the formula shown.

<em>Volume = length × width × height </em>

Since the length of the pool is 20 feet, the width is 15 feet, and the depth or height is 6 feet we can plug this information into the formula.

Volume = (20 feet) (15 feet) (6 feet) = 1,800 ft.³

Therefore, it will take 1,800 cubic feet of water to fill the pool.
