Answer:
(3x+2)(x+4)
Step-by-step explanation:
(3x+2)(x+4) = (3x)(x) + (3x)(4) + (2)(x) + (2)(4)
= 3x² + 12x + 2x + 8 *****
= 3x² + 14x + 8
You start by figuring it will be in the form of (3x + a)(x + b) because 3 doesn't factor. The two middle terms in the line followed by the stars must add up to 14x. And in (3x + a)(x + b), ab must be equal to the 8 on the end (the constant factor).
For most people, factoring takes a LOT of practice. And somethimes you just have to try a lot of factors before you hit the right combination. But if you do it enough, it really does get easier to 'see' the answer a lot of the time.
Hope this helped!

A camera shop's daily profit is given by P = 3x2 – 3x + 10, where x is the total number of
cameras sold in the day. If they only had profit of $70 today, how many cameras did they
sell?
Answer:
5 cameras they sell
Step-by-step explanation:
P = 3x² – 3x + 10 p = 70
3x² – 3x + 10 = 70
3x² – 3x - 60 = 0
x² - x -20 = 0
(x + 4) (x - 5) = 0
x can't be negative, x = 5
The no of cameras sold if A camera shop's daily profit is given by P = 3x² – 3x + 10, where x is the total number of cameras sold in the day. If they only had a profit of $70 today is 5.
What is equation?A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation. As in, 3x + 5 Equals 15, instances. Equations come in a variety of forms, including linear, quadratic, cubic, and others.
Given:
The equation, P = 3x² - 3x + 10,
If P = 70 then,
70 = 3x² - 3x + 10
x = 5 and -4 but the number of cameras can not be negative
Therefore, The no of cameras sold if A camera shop's daily profit is given by P = 3x2 – 3x + 10, where x is the total number of cameras sold in the day. If they only had a profit of $70 today is 5.

Xavier claims that the number of text messages he sends is proportional to the amount he owes on his monthly phone bill. He has listed the number of text messages sent and the amount he owed for a few months: January: 300 text messages sent; $15.00 owed February: 314 text messages sent; $15.70 owed March: 486 text messages sent; $24.30 owed April: 205 text messages sent; $10.25 owed Which of the following methods would help Xavier prove his claim? Select all that apply.
Answer:
Xavier could plot data points based on the number of text messages sent in each month and the amount owed to create a straight line on the graph starting at (0, 0.05).
Xavier could create a table listing the number of text messages sent in each of the months listed and the amount he owed for those months to test for equivalent ratios.

m= marbles (take note of my user name
Answer:
For each draw, the chances of getting a blue marble are 3 of 7; the chances of getting a red are 4 of 7.
The chances of drawing a blue on both draws is (3/7)^2 or 9/49, and the chances of getting red on both draws is (4/7)^2 or 16/49. But there are other possible outcomes which have to be considered to come to the correct answer.
There are 4 possible outcomes, as follows (although the chances of these outcomes are different):
Comb Chances
RR …….. 16/49
RB …….. 12/49
BR …….. 12/49
BB ……… 9/49
total …….. 49/49
So we can say that the chances of drawing red marbles on each draw are 16/49, and the chances of drawing blue ones on each draw are 9/49. But what about the chances of drawing either both red OR both blue?
I believe we can simply add the 2 probabilities together to come up with a probability of

Probability of two reds = 4/7 x 4/7 = 16/49 = 32.65%
Probability of two blues = 3/7 x 3/7 = 9/49
Probability of the same colour = 25 / 49 = 51.0 %

Identify the initial amount a and the rate of decay r (as a percent) of the exponential function y = 8(1 – 0.15). Evaluate the function
when t = 3. Round your answer to the nearest tenth.
Answer:
Initial amount = 8
Decay rate = 15%
Step-by-step explanation:
Given the exponential function :
y = 8(1 – 0.15)
The general form of an exponential Decay function is :
A = P(1 - r)^t
Where
A = final amout ; P = initial amount ; r = days cay rate ; t = time
Hence, comparing with the equation given :
P = 8 = initial amount
r = 0.15 = 0.15 * 100% = 15% = Decay rate

Line segment t and line segment r are parallel. Both line segments are reflected across the y–axis to form line segments t' and r'. . What is the distance, in units, between line segmentst' and r'? Select ONE correct answer.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but I would show you how to answer it.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
Reflection is the flipping of a figure about an axis. Reflection is a rigid transformation, that is it preserves the shape and size of the figure.
If the distance between Line segment t and line segment r is 5 units and then both line segments are reflected across the y–axis to form line segments t' and r'. The distance between the newly formed line segments t' and r' would still be 5 units

What is the value of q in the solution to this system of equations?
2m-5q=8
4m+2q=64
A.4
B.6
C.9
D.14
Answer:
4
Step-by-step explanation:
M,q 14,4
The value of q in the system of equations 2m-5q=8 and 4m+2q=64 is 4 thus option (A) is correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
As per the given system of equations,
2m-5q=8
4m+2q=64
Multiply by 2 into the equation 2m - 5q = 8
4m - 10q = 16
Subtract 4m - 10q = 16 by 4m+2q=64
-10 - 2q = 16 - 64
-12q = -48
q = 4
Hence"The value of q in the system of equations 2m-5q=8 and 4m+2q=64 is 4".
