Rewrite using the distributive property and GCF 16 + 40
Artist 52 [7]

The GCF of 16 and 40 is 8.

16/8 = 2

40/8 = 5

We can rewrite this using the distribute property like so:

<h3><u>8(2 + 5)</u></h3>

Using the distributive property:

16 + 40

16 + 40 = 56

We can also add inside the parentheses and multiply and we'll get the same answer.

8(7)

56

Mario says that the expression 4+3n² has four terms: 4, 3, n, and 2. Is he correct? explain.
stich3 [128]

Mario says that the expression 4+3n^2 has four terms: 4, 3, n, and 2. Mario is incorrect

<em><u>Solution:</u></em>

Given that the expression is:

4+3n^2

Given that, Mario says that the above expression has four terms

But Mraio is incorrect

Because the given expression has two terms only

4 is one of the term

3n^2 is another term

So there are totally 2 terms only

A term can be a signed number, a variable, or a constant multiplied by a variable or variables

Here 3 is a constant multiplied by n^2

So, 3n^2 is one term

Each term in an algebraic expression is separated by a + sign or - sign

Thus there are two terms in mario expression

What is the percent of change from 180 to 387
o-na [289]

To find the percent of change, subtract to find the amount of change

387 - 207 = 180. The increase is 207.

Then divide the amount of change by the original amount

207 ÷ 180 = 1.15

Change the decimal to a percent, and multiply the number by 100:

1.15 X 100 = 115

The answer is 115%
