Which expression is equivalent to -3x(x-4)-2x(x+3)?
Answers
Answer:
x(x^2 + 6)
Step-by-step explanation:
We are to simplify -3x(x-4)-2x(x+3). Begin by performing the indicated multiplication. We get -3x^2 + 12x - 2x^2 - 6x.
Combining like terms, we get -5x^2 + 6x, which is equivalent to
x(x^2 + 6)
Answer
=5x²+12x-6
Step-by-step explanation:
you multiply -3x(x-4)-2x(x+3)
=-3x²+12x-2x²-6
group like terms
=-3x²-2x²+12x-6
=-5x²+12x-6

Answers
Answer:
3. 31
4. 6
5. 7
6. No because the frequency table shows only ranges of times.
Step-by-step explanation:
3. Add up the number of students in each section of your table:
6 + 2 + 8 + 6 + 9 = 31
4. Only the first group ran under 9 minutes.
5. 8 students ran 1 mile in under 10 minutes (the first two sections)
15 students took 11 or more minutes to run 1 mile (the last 2 sections)
15 - 8 = 7
6. No, because the frequency table shows only ranges of times.
There are 31 students in PE class, 6 students ran 1 mile in under 9 minutes, 8 students are there who ran 1 mile in under 10 minutes than students who took 11 or more minutes to run that distance and no student ran a mile in exactly 12 minutes.
What is Statistics?A branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data
A frequency distribution table is a method to organize the data given so that it makes it more meaningful and easier to understand.
The given frequency table
Time Number of students
8:00-8:59 6
9:00-9:59 2
10:00-10:59 8
11:00-11:59 6
12:00-12:59 9
3. The number of students in the PE class
6+2+8+6+9
=31
4. Only the first group ran under 9 minutes which is 6 students
5. 8 students ran 1 mile in under 10 minutes
6+2=8
15 students took 11 or more minutes to run 1 mile
15 - 8 = 7
6. No, because the frequency table shows only ranges of times.
Hence there are 31 students in PE class, 6 students ran 1 mile in under 9 minutes, 8 students are there who ran 1 mile in under 10 minutes than students who took 11 or more minutes to run that distance and no student ran a mile in exactly 12 minutes.

Volume of hemisphere =
[tex] \frac{2}{3} \pi \: r {}^{3} [/tex]
Given volume =
[tex]18\pi \: cube[/tex]
[tex] \frac{2}{3} \times \frac{22}{7} \: {r}^{3} = 18 \times \frac{22}{7} [/tex]
So pi is there on both the sides so it will be cut from both LHS and RHS
[tex] \frac{2}{3} \times r {}^{3} = 18[/tex]
[tex]2 \times r {}^{3 } = 18 \times 3[/tex]
[tex]2 \times r {}^{3} = 54[/tex]
[tex]r {}^{3} = \frac{54}{2} [/tex]
[tex]r {}^{3} = 27[/tex]
[tex]r = 3[/tex]

A circle has a diameter of 36 cm. Which expression could represent the area of this circle in square cm?
Answers
Answer:
Step-by-step explanation:
You haven't given the choices but I believe the equation below could represent the area of the circle:
(pi ~ 3.14) * (18)^2
The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.

Step-by-step explanation:
In order to find the number of solutions, we have to expand both sides out first.
[tex]3(x - 2) + 7x = \frac{1}{2} (6x - 2)[/tex]
First, expand 3(x-2), which will obtain 3x-6.
Next, expand (1/2)(6x-2), which gives 3x - 1.
The result at this point should be as shown below:
[tex]3x - 6 + 7x = 3x - 1[/tex]
Now, we would shift all x terms to the left and all number terms to the right.
[tex]3x + 7x - 3x = - 1 + 6[/tex]
After simplifying, the final equation would be:
[tex]7x = 5[/tex]
This is a linear equation and it has one solution.
[tex]x = \frac{5}{7} [/tex]
Answer:
x = 5/7
