Enter the sum of the numbers as the product of their GCF and another sum.
Tpy6a [65]

Answer:

8

Step-by-step explanation:

Explanation: The GCF of 56 and 64 is 8 , as 8 goes into 56 exactly 7 times and into 64 exactly 8 times. 8(8)+7(8)=8(7+8).

Factor each polynomial. Look for a GCF first
weeeeeb [17]

Answer:

20. x\left(x-6\right)\left(x+8\right)

22. 2\left(x+1\right)\left(x+4\right)

24. 5m\left(m-1\right)\left(m+7\right)

Step-by-step explanation:

20. x^3+2x^{2} -48x

The GCF is x, so you group it out of the equation first.

x(x^{2} +2x-48)

Then, you find 2 numbers that will equal to 2 when you add them and will equal to -48 when you multiply them.

?+?=2\\?*?=-48

The two numbers would be -6 and 8. You then differentiate the squares.

x\left(x-6\right)\left(x+8\right)

22. 2x^{2} +10x+8

The GCF is 2, so you must group it out.

2(x^{2} +5x+4)

Find the two numbers that will equal to 5 when you add them and will equal to 4 when you multiply them.

?+?=5\\?*?=4

The two numbers would be 1 and 4. Finally, differentiate the squares.

2\left(x+1\right)\left(x+4\right)

24. 5m^{3} +30m^2-35m

The GCF is 5m, so you must group it out.

5m(m^2+6m-7)

Find the two numbers that will equal to 6 when you add them and will equal to -7 when you multiply them.

?+?=6\\?*?=-7

The two numbers would be -1 and 7. Finally, differentiate the squares.

5m\left(m-1\right)\left(m+7\right)

What is the square root of 225 and 226? Also what is a short cut I could use to figure this out more easily?
Reptile [31]
The square root of 255+266 is 241. I can't help you with shortcuts as I'm bad at explaining, but I'm sure there are websites that can help you.
