7.(03.02) What is the factored form of 3x2 + 5x – 12? (1 point) (3x + 3)(x + 4) (3x - 1)(x – 4) (3x + 4)(x - 3) (3x – 4)(x + 3)
Answer:
Hope it can help you... .
If u understand my answer, you can mark me as a brainlist.....
Answer:
(x + 3)(3x - 4)
Step-by-step explanation:
Given
3x² + 5x - 12
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 12 = - 36 and sum = + 5
The factors are + 9 and - 4
Use these factors to split the x- term
3x² + 9x - 4x - 12 ( factor the first/second and third/fourth terms )
= 3x(x + 3) - 4(x + 3) ← factor out (x + 3) from each term
= (x + 3)(3x - 4)
Thus
3x² + 5x - 12 = (3x - 4)(x + 3) ← in factored form

What is the rise between the points (0,0) and (8, 12)?
Answer:
8/12 or x+8 y+12
Step-by-step explanation:
The rise between the points (0,0) and (8,12) is 12.
What is the slope?The ratio of the vertical and horizontal changes between two points on a surface or a line is known as the slope.
Rise is the difference of y-coordinates of the points.
Therefore, the rise between the points (0,0) and (8,12) is:
12 - 0
=12
Hence, the rise between the points (0,0) and (8,12) is 12.

1) As you know, the area of a square is A = x , where for this problem, A is area in feet and x is the length of a side, in feet. If the length of a side is changing at a rate of 6 feet/minute when the length of a side is 4 feet, at what rate is the area changing?
What is the least number of degrees you could rotate a regular pentagon (5 equal side lengths) around its center so that it appears to be unchanged?
Answer:
Well, I'm not the smartest person, nor do I exactly know what you mean, but I have a wild guess that the least you could rotate it is 100 degrees.
Step-by-step explanation:
Considering the fact that it's sides are all equal, you could compare this to a square, which also has equal sides. Its angles are equal, too, so you could measure it's angles (100 degrees) and turn it that exact amount,
I hope this helps you, like I said, I don't exactly know what you are talking about, I am not studying that sort of thing yet.

Answer:
A, C, D, and F all apply.
Step-by-step explanation:
Simply divide the numerator by the denominator to calculate the rational number.
5/4 = 1.25
15/-12 = -1.25, not 1.25
15/12 = 1.25
-5/-4 = 1.25
-5/4 = -1.25, not 1.25
-15/-12 = 1.25

You purchase a music store for $115,000. The estimated monthly revenue is $5500 and you expect monthly costs are $3200. Let R represent revenue during the first t months . Write a linear model for R
9514 1404 393
Answer:
R = 5500t
Step-by-step explanation:
The estimated monthly revenue is said to be 5500 per month. Then for t months, the revenue R will be ...
R = 5500t
_____
Additional comment
We expect costs to be C = 3200t, so profit is ...
P = R -C
P = 5500t -3200t
P = 2300t
At that rate, it will be 50 months before enough profit is earned to pay for the initial cost of the store.

Answer:
A. n = 1/63
B. k = 13/3
C. g = 5
D. w = 21/17
Step-by-step explanation:
A. 9n = 15/7 - 2
9n = 15-14/7
9n = 1/7
n = 1/7 ÷ 9
= 1/7 × 1/9
n = 1/63
B. 1/3 = k - 4
1/3 + 4 = k
1+12/3 = k
13 /3 = k
k = 13/3
C. g - 2/5g = 3
5g-2g/5 = 3
3/5g = 3
g = 3 ÷ 3/5
= 3 × 5/3
= 15/3
g = 5
D. 3/7w + 2w = 3
3w+14w/7 = 3
17/7w = 3
w = 3 ÷ 17/7
= 3 × 7/17
= 21/17
w = 21/17

1. What is the value of s?
A. 8
B.16
C.16|2
D.32
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex] \cos(30°) = \frac{16 \sqrt{3} }{s} \\ [/tex]
[tex] \frac{ \sqrt{3} }{2} = \frac{16 \sqrt{3} }{s} \\ [/tex]
Inverse both sides
[tex] \frac{2}{ \sqrt{3} } = \frac{s}{16 \sqrt{3} } \\ [/tex]
[tex] \frac{s}{16 \sqrt{3} } = \frac{2}{ \sqrt{3} } \\ [/tex]
Multiply sides by 16√3
[tex]16 \sqrt{3} \times \frac{s}{16 \sqrt{3} } = 16 \sqrt{3} \times \frac{2}{ \sqrt{3} } \\ [/tex]
[tex]s = \frac{2 \times 16 \times \sqrt{3} }{ \sqrt{3} } \\ [/tex]
[tex]s = 32[/tex]
Thus the correct answer is Option D .

Find the missing side-geometry!!
Answer:
12cm
Step-by-step explanation:
pythagorean theorem!
a^2 + b^2 = c^2
7^2 + b^2 = 13^2
49 + b^2 = 169
49 - 49 + b^2 = 169 - 49 (whatever you do to one side, you do to the other side)
b^2 = 147 (square root)

1. Find the volume of the shape below:

5.8 in
12 in
Answer:
208.8 inches is the answer
Based on concepts related to the volume of prisms, the volume of the shape depicted with the dimensions shown in the figure is equal to 208.8 square inches. #SPJ2
How to calculate the volume of a prism-like element
Prisms are tridimensional elements whose volume is equal to the product of area of its base, in square inches, and its height, in inches. The base of the shape is certainly a rectangle, whose area is equal to the product of its width and length, both in inches.
Therefore, the volume of shape is:
V = (12 in) · (5.8 in) · (3 in)
V = 208.8 in³
