what are the steps to simplifying radical expressions?
Answer:
Step 1: Find the prime factorization of the number inside the radical.
Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind.
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical.
Step 4: Simplify the expressions both inside and outside the radical by multiplying.

What is this 8=a+3+4
[tex]\bf Step-by-step~explanation:[/tex]
If we were to solve for a, we will need to isolate the variable.
[tex]\bf Step~1:[/tex]
Add the like terms on the right side of the equation together.
[tex]\bf 8=a+3+4\\8=a+7[/tex]
[tex]\bf Step~2:[/tex]
Subtract 7 from both sides to move 7 to the other side.
[tex]\bf 8(-7)=a+7(-7)\\1=a[/tex]
[tex]\bf Step~3:[/tex]
Rewrite the equation so that the variable is at the beginning. This is the format most teachers prefer.
[tex]\bf 1=a\\a=1[/tex]

Construct a frequency distribution and a frequency histogram for the data set using the indicated number of classes. Describe any patterns. Number of classes: 8 Data set: Finishing times (in seconds) of 20 male participants in a 5K race
Answer and Explanation:
Number of classes = 8
Highest value =2300
Lowest value = 1250
Class width= highest value – lowest value / number of classes
= 2300 – 1250/8
= 131.25 = 132
So, we can write class as 1250+132=1382
Class frequency
1250-1382 2
1382-1514 3

The students at Woodward Elementary voted for a school mascot. The falcon won with 5/8 of the votes and the eagle came second with 1/3 of the remaining votes. If 536 students voted for a mascot, how many students voted for the eagle?
Answer:
178.67
Step-by-step explanation:
One third written as a fraction is 1/3. You can also write it as a decimal by simply dividing 1 by 3 which is 0.33.
If you multiply 0.33 with 536 you will see that you will end up with the same answer as above.
You may also find it useful to know that if you multiply 0.33 with 100 you get 33.33. Which means that our answer of 178.67 is 33.33 percent of 536.

Solve the equation
-2(2x - 4) = 4x
Write it step by step. I really need help
Answer:
x = 1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2(2x−4)=4x
(−2)(2x)+(−2)(−4)=4x(Distribute)
−4x+8=4x
Step 2: Subtract 4x from both sides.
−4x+8−4x=4x−4x
−8x+8=0
Step 3: Subtract 8 from both sides.
−8x+8−8=0−8
−8x=−8
Step 4: Divide both sides by -8.
9x + 5 - 3x = 5x - 14
Answer: The answer is x = -19
Answer:
-19
Step-by-step explanation:
9x - 5x -3x = -14 -5
1x = -19

Prove that if 5(m - 1) = -25, then m = -4.
Answer:
The equation is true
Step-by-step explanation:
First, input -4 instead of m in the equation:
5(-4 - 1) = -25
Then, distribute:
-20 - 5 = -25
Finally, simplify:
-25 = -25
This equation is true, and that's how you prove it.
Hope this helps!
Answer:
M= -4
Step-by-step explanation:
1. Distribute the 5 into the parentheses
5m-5=-25
2. Now add 5 on both sides
5m=-20
3. Now divide 5 by -20
m=-4
Residents who live in the city receive power from the city’s power plant. If the city is a square, approximately how wide is the city if the area is 200 square miles?
find the zero of the function h(x) = 4x+2
Answer:
[tex]x=-1/2=-0.5[/tex]
Step-by-step explanation:
So we have the function:
[tex]h(x)=4x+2[/tex]
To find the zero(s) of a function, set the function equal to 0 and solve for x. So:
[tex]0=4x+2[/tex]
Subtract 2 from both sides:
[tex]-2=4x[/tex]
Divide both sides by 4:
[tex]x=-1/2=-0.5[/tex]
So, the zero of the function is -0.5.
This means that the graph (a line) crosses the x-axis at (-0.5, 0).

a. About how far is it from Amarillo to Oklahoma City? Explain your reasoning. b. Driving at a constant speed of 70 miles per hour, will it be possible to make this trip in 3 hours? Explain how you know.
Answer:
They are 260 miles apart. No it would not be possible.
Step-by-step explanation:
If they are 260 miles apart and you drive at a constant speed on 70mph. You will have to 260/70 which = 3.7 or 4 so it would not be possible.
Amarillo and Oklahoma City are [tex]260[/tex] miles apart.
It is not possible to make this trip in [tex]3[/tex] hours.
By using any geographical tool, such as the local map or you can use internet too to find the distance between Amarillo and Oklahoma City.
Amarillo and Oklahoma City are [tex]260[/tex] miles apart.
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Time = \frac{Distance}{Speed}[/tex]
[tex]Time = \frac{260}{70}[/tex]
Time [tex]= 3.714[/tex] hours
So, it is not possible to make this trip in [tex]3[/tex] hours.

The actual distance between the library and train station is 500 ft. Explain how you
could find the distance between them in centimeters on the map.
Answer:
15,420 cm
Step-by-step explanation:
Given the actual distance between the library and train station to be 500 ft, to find the distance between them in centimeters, we ill convert 500 ft to cm as shown;
Given the conversion:
1 ft = 30.48cm
500ft = x cm
Cross multiply
x cm * 1ft= 30.48 cm * 500ft
x cm = 30.48 cm * 500ft/1ft
x cm = 15,240 cm
Hence the distance between them in centimeters on the map is 15,420 cm
