11. Perimeter = All Sides added together.

Remember there are two of each side with the expression.

Expression: 3b + 3b + b+a + b+ a

To simplify collect all like terms (ones with a common letter or are the same)

Simplified expression: 8b + 2a

You got the expression by adding all sides together then simplifying by collecting like terms.

I will do the rest as comments on this post.

How should the decimal point in 0.937 change to get the correct answer to 0.937 ÷ 10²?

A. move it 2 place to the right

B . move it 2 places to the left

C .move it 3 places to the right

D .move it 3 places to the left

Answers

Answer:

B.

Step-by-step explanation:

When moving a decimal point 2 places to the right you are multiplying. When moving it to the left you are dividing. In this case we are moving 2 places to the left which the exponent 2 is representing. If you were to move 3 places to the right or left you would need to have a three as your exponent.

Which number line shows 1 to 4 divided into thirds?

Answers

Answer:

Line 1.

Step-by-step explanation:

This is because in order for it to be considered thirds, the third has to equal a whole. Line one goes:

1/3      2/3      3/3

This is split into thirds

The required number line that represents the dividend of the three is the fourth line. Option D is correct.

Given that.
To determine the line that has a dividend of 3.

What is a number line?

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
Line 1 has a dividend of 2,
Line 2 has a dividend of 5
Line 3 has a dividend of 4
Line 4 has a dividend of 3

Thus, the required number line that represents the dividend of the three is the fourth line. Option D is correct.
