Answer:
(x +6)(3x +4)
Step-by-step explanation:
The usual approach to this is to look for factors of the product 3·24 that have a sum of 22.
72 = 1·72 = 2·36 = 3·24 = 4·18 = 6·12 = 8·9
Sums of these factor pairs are 73, 38, 27, 22, 18, 17.
Now, you can rewrite the expression splitting the middle term into two parts:
3x² +4x +18x +24
x(3x +4) +6(3x +4) . . . . . . factor by grouping
(x +6)(3x +4) . . . . . . . . . . your factored form

Additional comment
I find this method easiest to explain and to do without error. There are various "X" methods in which you write the product at the top (3·24) and the sum at the bottom (22), then fill in the sides with the factors having that product and sum (4, 18). When the leading coefficient is not 1, there are methods added to this that get you to the correct factors.
One such method is to use the leading coefficient inside parentheses: (3x+4)(3x+18) Then divide that product by the leading coefficient:
(3x +4)(3x +18)/3 = (3x +4)(x +6).
In some cases, each of the binomials needs to be divided by part of the leading coefficient; not the whole thing, as here.

~ N(,)
What is the probability that the average of 35 numbers will be less than 7.9?
Answer:
22.5
Step-by-step explanation:
The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.
(a) Distribution of X is uniform distribution X to U(4,11).
(b) Sample size (n) = 35, distribution of mean would be moderate with value = (4+11)/2 = 7.5
Standard deviation = √ [(11-4)^2/(12*35] = 0.3415
Now
x to N (7.5, 0.3415)
(c) We have to find probability that the average of 35 numbers will be less than 7.9.
P(x < 7.9) = P(x < 7.9; 7.5; 0.3415)
Z = (7.9 -7.5)/0.3415
Z = 1.1713
P(x< 7.9)= P(Z < 1.1713)= 0.87932.
Thus, The required Distribution, selection and probability is X to U(4,11), x to N (7.5, 0.3415) and 0.87932 respectively.

Can someone help me find m
Answer:
69 degrees
Step-by-step explanation:
m is a point, if your trying to find lkh, is 69
lkm=111, and jkl=180, so 180-111=jkm
jkm=69
angles that are diagonal from each other are the same degree
lkh=69
hope this helps, if not see me in the commnets
HOPE THIS HELPS, BRAINLIEST PLEASE
Answer:
m < LKH = 69°
Step-by-step explanation:
Given that m < LKM = 111° and that:
<LKM and <LKH are adjacent angles as they share the same vertex, point K, and same ray between them, KL:
Then we can assume that m < LKM and m < LKH are supplementary angles whose sum = 180°.
Therefore, we can establish the following equation:
m < LKM + m < LKH = 180°
111° + m <LKH = 180°
Subtract 111° from both sides to solve for m < LKH:
111° - 111° + m <LKH = 180° - 111°
m < LKH = 69°
Therefore, the measure of < LKH is 69°.

6. A linear function f(x) contains the coordinates (-9, 4) and (6,4). Joy says f(x) is a horizontal
line, and Lu says f(x) is a vertical line. Which student correctly described the function?
Explain.
Answer: Horizontal Line
Step-by-step explanation:
Joy is correct. This is a horizontal line. It has the same y coordinates so it will be a horizontal line.
Joy is saying correct by saying it is a horizontal line.
What is coordinates?Coordinates are a set of values which helps to show the exact position of a point in the coordinate plane.
Given:
coordinates (-9, 4) and (6,4)
If we plot these point on the graph it will have the y- coordinates same for both coordinates.
Also, if the graph have same y- coordinates then the line joining these points are horizontal in nature.
Hence, Joy is saying correct by saying it is a horizontal line.

What is the midpoint of a line with endpoints (6,5) and (14,7), (Your answer
should be an ordered pair)
Answer:
Midpoint = (10,6)
Step-by-step explanation:
Using Coordinates: X(6,5) and Y(14,7)
Using the midpoint formula: M = (X1 +Y1)/2, (X2 + Y2)/2
Midpoint of XY = (6 + 14) / 2, (5 + 7) / 2
Midpoint of XY = (20) / 2, (12) / 2
Therefore the midpoint of XY is (10,6)
