Answer:

Area: 5x + 10

Perimeter: 2x + 14

Step-by-step explanation:

Area = length times width

Perimeter = length (2) + width (2)

<u>Area:</u>

Multiply the length be the width. That gives you 5 (x + 2).

Then use the distributive property to simplify this expression. That gives you 5x + 10.

<u>Perimeter:</u>

Multiply the width by 2. That gives you 10.

Multiply the length by 2. That gives you 2x + 4

Add the 2 together. That gives you 10 + 2x + 4.

Combine all like terms. That gives you 2x + 14.

raketka [301]

Answer:

Step-by-step explanation:

Equation given

tan(3B-32 ) = cot ( 5B +10 ) = tan [ 90 - ( 5B + 10 ) ]

tan(3B-32 ) = tan  (90 - 5B - 10 )

(3B-32 ) =  (90 - 5B - 10 )

8B = 32 + 80

B = 14° .

Georgia [21]

Answer:

Only 16 problems correct

Step-by-step explanation:

Well I thought that since 80% is  4/5 then I should do 20 divided by 5 which will get me 4 and since I'm doing 4/5 I should go all the way up to 80% of 20 which will get me 16.

I'm not making that much sense but

Hope this helps :)

DENIUS [597]

Answer:

This is a ratio table,so therefore there is always a pattern.

Step-by-step explanation:

In order to solve,you have to find the constant in the question,such as 30,40,50,and 60.The constant in this example is 10.When the constant is <u>not</u> even,or the numbers are <u>not</u> even,that's the time you pull out your notebook multiplication chart.Look at the numbers,and see if those numbers are on the chart.If all of them are on the chart,then see if one or both of the multiplicable numbers fall under the category of your variables.If all are under one number,then that number is your answer.
