Step-by-step explanation:

x² + 2x - 24 = (x + 6)(x - 4) = x² - 4x + 6x - 24 = x² + 2x - 24

True.

x² - 8x + 15 = (x + 5)(x +3) = x² + 3x + 5x + 15 = x² + 8x + 15

False.

3x² + 4x + 1 = (3x + 1)(x + 1) = 3x² + 3x + x + 1 = 3x² + 4x + 1

True.

5x² - 2x - 3 = (5x + 3)(x - 1) = 5x² - 5x + 3x - 3 = 5x² - 2x - 3

True.

4x² - 49 = (2x - 7)(2x + 7) = 4x² + 14x - 14x - 49 = 4x² - 49

True.

She wants you to find the mean, mode, and median of the given data. How did you solve each part?

Answers

Answer:

Mean: 3.5263157894737

Median: 3

Mode: 3

Step-by-step explanation: The mode is 3 because the mode is for which number pops up the most, which is 3.

I got the median by crossing out 8 from the left and the right of the number set and got 3 as the last number.

I got the mean by adding up all the numbers and divided it by the amount of numbers in the set.

The value of x is ?

Answers

Answer: X = 42

Steps:
(3x + 12) + x = 180
3x + 12 + x = 180
4x + 12 = 180
4x = 180 - 12
4x = 168
x = 168/4
x = 42

Check:
(3x + 12) + x = 180
3x + 12 + x = 180
3(42) + 12 + 42 = 180
126 + 12 + 42 = 180
180 = 180 ✅

Answers

Answer:

all numbers

Step-by-step explanation:

3x - 5(x + 6) = -2x -2(5 + 10)

Distribute on both sides.

3x - 5x - 30 = -2x - 10 - 20

Add 2x to both sides.

-2x - 30 = -2x - 30

-30 = -30

Since we get a true statement after only doing legal steps to solve the equation, the equation has an infinite number of solutions.

Rectangle area = length * width

Width = (18x^2-42x)/6x
Width = 3x-7

Let’s make sure
Area = length * width
Area = 6x * (3x-7)
Area = 18x^2 -42x which is true
That mean width = 3x-7

Is 4/5 greater or less than 45/100 how do you know

Answers

Answer:

4/5 is grater than 45/100

Step-by-step explanation:

Why?

because in percentage you make the bottom # a 100 one of them already has that and when it has 100 on the bottom it tells you that the top # is the percentage so 45/100 is 45%

now to make 4/5 a percentage what times 5 = 100?

20 does

so you times the top and bottom by 20

4*20= 80

now your fraction is 80/100 (top # tells you the %)

it's 80%

80% is grater than 45%

Answer:

4/5 is greater than 45/100.

Step-by-step explanation:

In order to figure it out, you need to make both fractions have common denominators. In order to do that, you figure out this:

5 times what equals 100? It's 20.

With fractions in this situation, whatever you do to the top, you have to do to the bottom. So, you multiply 4 times 20, which is 80.

In the end, you would end up with these two fractions:

80/100 and 45/100.

Obviously, 80/100 is greater than 45/100. In the beginning, 80/100 was originally 4/5. Therefore, 4/5 is greater than 45/100.
