Answer:

Six numbers have perfect square factors

Step-by-step explanation:

The numbers with perfect square factors are those numbers that have perfect squares as one of the numbers that can divide them.

They include:

4 = 2 * 2

16 = 4 * 4

36 = 6 * 6

49 = 7 * 7

64 = 8 * 8

81     = 9* 9

These numbers above have perfect square factors because they are formed from integers that multiply themselves.

How do I find a common denominator for a complex faction when one denominator is 2m-1 and the other is 2m+5
ratelena [41]
The best option is to multiply them together, there would be no value that is common between the two, (2m - 1)(2m + 5), and leave it in this form.

However, there is a second method.
Notice how between the two sits a difference of 6.
You can manipulate one of the fractions to render the same denominator and work from there.

Which square root is between 4 and 5
shusha [124]
Answer:
I’m not sure what you mean by divided, but the square root of 24 would be between 4 and 5.

Explanation:
I translated 4 and 5 into square roots, being the square root of 16 (4^2) and the square root of 25 (5^2).
4 is equal to the square root of 16 just as 5 is equal to the square root of 25.
Of the given square roots in the answers, only the square root of 24 was between the square roots of 16 and 25. Therefore, the square root of 24 is between 4 and 5.

A 20-foot ladder leans up against the side of a building so that the foot of the ladder is 10 feet from the base of the building
harina [27]

Answer:

17.3

Step-by-step explanation:

To solve this equation, you need to use the pythagorean theorem which is:

a^{2} +b^{2}= c^{2}

a= length

b= height

c= hypotenuse

First, substitute in your values for the equation:

10^2+b^{2} =20^{2}

Then, use the squares in the equation:

100+b^{2} =400

Then, subtract 100 from both sides to isolate b:

b^{2} =300

Finally, square root both sides to get your answer:

b=17.3205080757

Then round to the nearest tenth which gives you 17.3.

What are the slope and the y-intercept of the linear function that is represented by the equation 8x - 2y = 5?
ivann1987 [24]
Y=mx+b is the formula you need to get it in
start with the equation 8x-2y=5
so we want to get y by itself and everything else on the right side of the equation. to do this first subtract -8x from the left side and put it on the right side. this step would look like this:
8x-2y=5
-8x-2y=5 -> -2y=5-8x
-------------

next take and divide -2 from both sides of the equation. this would look like this:
-2y= 5 -8x
÷-2y=÷-2÷-2 -> y= -5/2 +4x
-------------------
so your new equation is y=4x-5/2 y=mx+b tells you the slope and y-intercept. m=slope and b=y-intercept. so in this case 4 is your slope and -5/2 is your y-int
