Answer:
6x^2 + 6x + 6x + 6
Step-by-step explanation:
You're cross multiplying the numbers on the left with the numbers on the right. Here is the order you multiply them in to eliminate the brackets, aka simplify the equation.
Step 1: (this ....) x ( this ....)
Step 2: (this ....) x (.... this)
Step 3: (.... this) x (this ....)
Step 4: (.... this) x (.... this)
REMEMBER!! When you multiply numbers with x's in them, make sure that you're multiplying the X's together too. For example, 2x times 3x is 6x^2 NOT 6x. Why? x times x is x^2 (aka x squared)

Step-by-step explanation:
slove for x 10(x-2)=-20
Answer:
x=0
Step-by-step explanation:
10(x-2)=-20
10x-20=-20 Distribution
10x=0 add 20 to both sides
x=0 divide by 10 on both sides
Step-by-step explanation:
10(x-2)=-20
10x-20=-20
10x=-20+20
x=0/10=0

What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth.
A) 7.2
B) 6.0
C) 2.8
D) 6.3
Answer:
We conclude that the length of LM if L(3,4) and M(1,-2) will be:
[tex]d = 6.3[/tex]
Hence, option D is correct.
Step-by-step explanation:
Given
L(3,4)M(1,-2)Determining the length of LM
(x₁, y₁) = (3, 4) (x₂, y₂) = (1, -2)The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)
[tex]=\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}[/tex]
[tex]=\sqrt{2^2+6^2}[/tex]
[tex]=\sqrt{4+36}[/tex]
[tex]=\sqrt{40}[/tex]
[tex]=\sqrt{4\times 10}[/tex]
[tex]=\sqrt{2^2\times \:10}[/tex]
[tex]=2\sqrt{10}[/tex]
[tex]=6.3[/tex]
Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:
[tex]d = 6.3[/tex]
Hence, option D is correct.

Answer:
A. y = 91.1765x - 346.5708B. 64 lbsStep-by-step explanation:
Part AUse the data in the table to get the best fit line, with equation:
y = mx + bTo do so follow the steps:
1. Let the Height be x and the Weight be y
Sum x and y
∑x = 5.3 + 5.4 + 5.3 + 6 = 22∑y = 140 + 150 + 130 + 200 = 6202. Sum x² and xy
∑x² = 5.3² + 5.4² + 5.3² + 6² = 121.34∑xy = 5.3*140 + 5.4*150 + 5.3*130 + 6*200 = 34413. Calculate m, considering n = 4 (number of data values)
m = (n∑xy -∑x∑y)/(n∑x² - (∑x)²) = (4*3441 - 22*620)/(4*121.34 - 22²) = 124/1.36 = 91.17654. Calculate b:
b = (∑y - m∑x)/n =(620 - 91.1765*22)/4 = -1385.883 /4 =-346.4708We got the best line fit formula:
y = 91.1765x - 346.5708Part BFinding y for x = 4.5:
y = 91.1765*4.5 - 346.5708 = 63.72345 ≈ 64 lbsthiannon is having a party. A total of 20 people are coming, How many pizzas

The volume of this cylinder is 2700π(cubed)
Find the length of the radius, r.
Give your answer as a surd in its simplest form.
r ?
150cm is the height
Given that,
The volume of the cylinder, [tex]V=2700\pi\ cm^3[/tex]
The height of the cylinder, h = 150 cm
To find,
The radius of the cylinder.
Solution,
The formula for the volume of the cylinder is given by :
[tex]V=\pi r^2 h\\\\r=\sqrt{\dfrac{V}{\pi h}}\\\\r=\sqrt{\dfrac{2700\pi }{\pi \times 150}}\\\\r=4.24\ cm[/tex]
So, the radius of the cylinder is 4.24 cm.

Solve the equations in Parts A and B using inverse operations. Check your solutions. In your final answer, include all of your work.
Part A:
[tex]2x^2+5=13[/tex]
Part B:
[tex]2x^{3} - 13 = 5[/tex]
Answer:
A) ±2
B) 2.08
Step-by-step explanation:
A) Given the equation
2x² + 5 = 13
Add the additive inverse of 5 to both sides
2x² + 5 + (-5) = 13 + (-5)
2x² + 5 - 5 = 13 - 5
2x² = 8
x² = 4
x= ±√4
x = ±2
Hence the value of x is ±2
b) 2x³-13 = 5
Add the additive inverse of -13 to both sides
2x³-13 + 13 = 5 +13
2x³ = 18
x³ = 18/2
x³ = 9
x = ∛9
x= 2.08
Hence the value of x is 2.08

Step-by-step explanation:
A cognitive psychologist studying reading comprehension wanted to know what would happen if all college students were taught better reading strategies. She obtained a sample of 40 college students from the introductory psychology class and taught 20 of them effective reading strategies. The other 20 students were given a placebo treatment. She then gave all 40 students a standardized reading comprehension test. The mean score on the reading test for those taught the reading strategies was 49, with a standard deviation of 4 The mean score for those receiving the placebo treatment was 44, with a standard deviation of 3.8. Identi the independent variable in this study.
A) scores on the reading comprchension test
B) the sample of 40 college students
C) the reading strategies class
D) the treatment group (placebo or reading strategies)
Answer:
D.the treatment group (placebo or reading strategies)
Step-by-step explanation:
This cognitive psychologists wants to find out if better reading strategies when taught to students would have any effect on their test scores.
So the dependent variable in this experiment would be the test scores that she wants to find from the test.
While the independent variable would be the treatment group which is the placebo or treatment. The psychologist wants to measure outcomes in this dependent variable using changes in the independent variable (placebo/treatment).
The random variable X is exponentially distributed, where X represents the waiting time to see a shooting star during a meteor shower. If X has an average value of 85 seconds, what are the parameters of the exponential distribution
Answer:
the parameters are [tex]\lambda = \frac{1}{85} , \mu = 85, \sigma = 85[/tex]
Step-by-step explanation:
The computation of the parameters of the exponential distribution is as follows:
Given that
X has an average value of 85 seconds
So, [tex]\mu[/tex] = mean = 85
[tex]\lambda = \frac{1}{\mu}\\\\= \frac{1}{85}[/tex]
[tex]\sigma = \mu = 85[/tex]
In the case of the exponential distribution, the mean would be equivalent to the standard deviation
So, the parameters are [tex]\lambda = \frac{1}{85} , \mu = 85, \sigma = 85[/tex]
