B. 4(2a + 5)
C. 4(4a + 16)
D. 4(4a + 5)

Answers

The expression 8a + 20 is equivalent to the expression 4(2a + 5). Then the correct option is B.

What is an equivalent expression?

The equivalent is the expression that is in different forms but is equal to the same value.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ 8a + 20

Factorize the terms of the expression, then we have

⇒ 4 × 2a + 4 × 5

Take 4 common from both terms, then we have

⇒ 4 × 2a + 4 × 5

⇒ 4 (2a + 5)

The expression 8a + 20 is equivalent to the expression 4(2a + 5). Then the correct option is B.

Find 6% of $5900000 to the nearest cent

Answers

Answer:

$354,000

Step-by-step explanation:

Since six percent in decimal is .06, all we have to do is multiply that by 5900000. When multiplied this would leave our answer to be $354,000. This is the answer unless we're missing any decimals, that would relate to the part of the question where it says round to the nearest cent.

PLZ ANSWER!!!!!! choose the answer. subtract. express your answer in simplest form.

you run 1 3/4 mile each day your friend runs 4 times as far as you do how far does your friend run each day

Answers

Answer:

7 miles your friend run each day.

Step-by-step explanation:

As per the statement:

You run 1(3)/(4) mile each day.

⇒ you run each day = (7)/(4) miles.

It is also given that; Your friend runs 4 times as far as you do.

"4 times as far as you do" means 4 * (7)/(4) = 7 miles

⇒ Your friend runs each day = 7 miles.

therefore, 7 miles your friend run each day
You have to multiply 1 3/4 and 4 so you can't multiply an mixed fraction with an improper fraction so 1 3/4 becomes 7/4 and now you get 28/16 and simplified it would be1 3/4
