Answer:
a) x^2 - x -12
b) 2s^2 - 16s + 24
c) 8s^2 - 8s -48
d) 4x^2 - 16x + 16
Answer:
a. x^2 - x - 12
b. 2s^2 - 16s + 24
c. 8s^2 - 8 - 48
d. 4x^2 - 16 + 16
Step-by-step explanation:
You need to use distributive property find the answer.
(x + 3)(x - 4)
>> (x)(x) = x^2
>>(x)(-4) = -4x
(3)(x) = 3x
(3)(-4) = -12
The result will be x^2 -4x + 3x -12
You can simplify this by adding the like terms:
x^2 -4x + 3x -12
>> x^2 - x - 12
Just do the same for the rest of them by using distributive property.
Hope this helps! Have a great day! Also, let me know if you need an explanation for the rest of them too!

I think the answer should be C
Answer: A
(2, -4) and (0,4);
x, y x, y
A. y = -4x +4; substitute the pairs
(2,-4)
-4 = -4(2) + 4 = -4; -4 = -4
(0,4)
4 = -4(0) + 4 = 4; 4 = 4
B. y = -4x - 4
(2, -4)
-4 = -4(2) - 4 = -12; -12 ≠ -4
(0,4)
4 = -4(0) - 4 = -4; -4 ≠ 4
C. y = 4x - 4
(2, -4)
-4 = 4(2) - 4 = 4; 4 ≠ -4
(0,4)
4 = 4(0) - 4 = -4; -4 ≠ 4
D. y = 4x + 4
(2, -4)
-4 = 4(2) + 4 = 12; 12 ≠ -4
(0,4)
4 = 4(0) + 4 = 4; 4 = 4
Answer A works out for both ordered pairs.

Malik digs a hole at a rate of 2/3 feet every 15 minutes. After digging for 60 minutes, Malik places a shrub in the hole that fills exactly 5/6 feet of the hole. Relative to ground level, what is the elevation of the hole after placing the shrub in the hole? Enter your answer as a mixed number in simplest form by filling in the boxes.
Answer:
15/6
Step-by-step explanation:
(20/9) ft of the hole is elevated after the shrub was placed.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is that Malik digs a hole at a rate of 2/3 feet every 15 minutes. After digging for 60 minutes, Malik places a shrub in the hole that fills exactly 5/6 feet of the hole.
In 15 minutes, the depth of hole digged is (2/3) feet.
In 1 minute, the depth of hole digged is {(2/3)/15} feet.
In 60 minutes, the depth of hole digged will be {(2/3)/15} x 60 = 8/3 ft.
The hole filled after placing the shrub will be -
(5/6) x (8/3)
5/6 x 8/3
5/3 x 4/3
20/9
Therefore, the (20/9) ft of the hole is elevated after the shrub was placed.

A community swimming pool is a rectangular prism that is 30 feet long, 12 feet wide, and 5 feet deep. The wading pool is half as long, half as deep, and the same width as the larger pool.
How many times greater is the volume of the swimming pool than the volume of the wading pool?
Enter your answer as a number, like this: 42
HELLLLPPPP PLEASEEEEEE
Answer:
The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.
Step-by-step explanation:
By definition of rectangular prism, we get the respective formulas for the volumes of the community swimming pool and the wadling pool, respectively:
Community swimming pool
[tex]V_{c} = l\cdot w\cdot h (1)[/tex]
Wading pool
[tex]V_{w} = \left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w (2)[/tex]
Where:
l – Length of the swimming pool, measured in feet.
h – Depth of the swimming pool, measured in feet.
w – Width of the swimming pool, measured in feet.
[tex]V_{c}[/tex] – Volume of the community swimming pool, measured in cubic feet.
[tex]V_{w}[/tex] – Volume of the wading swimming pool, measured in cubic feet.
The ratio of the volume of the community swimming pool to the volume of the wadling pool is:
[tex]\frac{V_{c}}{V_{w}} = \frac{l\cdot w \cdot h}{\left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w} (3)[/tex]
[tex]\frac{V_{c}}{V_{w}} = \frac{1}{\frac{1}{4} }[/tex]
[tex]\frac{V_{c}}{V_{w}} = 4[/tex]
The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.

What is the slope. Please help.
Answer:
The slope is 5
Step-by-step explanation:
Our equation:
y = mx + bGiven equation:
y = 5x + 4Now, let's compare both equations to see which is the slope.
=> y = mx + b = y = 5x + 4
We can clearly see that m = 5.
Therefore, the slope is 5.

What is the range of possible sizes for side x? _ < x < _
Answer:
0.5 < x < 16.5
Step-by-step explanation:
The third side of the triangle must be longer than the difference of the other two sides:
x > (8.5 -8.0)
x > 0.5
And it must be shorter than their sum:
x < (8.5 +8.0)
x < 16.5
The third side must be in the range ...
0.5 < x < 16.5
_____
These limits are a direct consequence of the triangle inequality, which requires the sum of the two shortest sides exceed the length of the longest side.
