Answer:

3(3a-6b+7c)

Step-by-step explanation:

We are asked to factor out GCF of expression 9a-18b+21c using distributive property.

We can see that greatest common factor of each term of our given expression is 3.

3\cdot 3a-3\cdot 6b+3\cdot 7c

Using distributive property a(b+c)=ab+ac, we will factor out 3 from our expression as:

3(3a-6b+7c)

Therefore, our required expression would be 3(3a-6b+7c).

The greatest common factor of 9, 18 and 21 is 3 so that is the number that we'll factor out

to do this divide all three numbers by 3 to get

3(3a-6b+7c)

I hope I've helped!

Make a conjecture about the next item in the sequence. 6, 9, 7, 10, 8?
inessss [21]

Answer:

"The next term should be 11"

Step-by-step explanation:

If we look closely at the sequence we can see:

second term is 3 more than previous

third term is 2 less than previous

fourth term is 3 more than previous

fifth term is 2 less than previous

We can see a pattern. To get next terms, we add 3, to get next to that, we subtract 2. It goes on like this.

Since 4th term to 5th term is "subtracting 2", logically 5th to 6th term (the term we are wanting) should be "add 3". So the term after 8 would be 11

The next term would be 11

one leg of a right triangle has length 7. the lengths of the other two sides are whole numbers. the length of the other leg is ?
zalisa [80]
Sets of three integers that could be right triangles are called pythagorean triples. the only pythagorean triple including 7 is 7, 24, and 25. so the length of the other leg is 24 and the length of the hypotenuse is 25. hope this helped!
