This is the formula you would use to calculate how many tiles you would need.

# of tiles you need = Total square footage ÷ square footage of each tile 


Total square footage: 69x69 = 4761 square feet
Square footage of each tile = 2x2 = 4 square feet

# of tiles you need =
4761 ÷ 4 = 1190.25 

You will need 1190.25 tiles.

7 - (2x + 1) + 4x<br> please show solving steps as well
xeze [42]

Answer:

2x + 6

Step-by-step explanation:

7 - (2x + 1) + 4x

Distribute the negative inside 2x+1

7 - 2x - 1 + 4x

Remind that <u>negative</u><u> </u><u>multiply</u><u> </u><u>negative</u><u> </u><u>must</u><u> </u><u>equal</u><u> </u><u>positive</u><u>.</u>

variables cannot sum/add/subtract with constants.

They must be the same terms.

4x - 2x - 1 + 7 \\ 2x + 6

Therefore, our answer is 2x+6

The midpoint of . is the point M, where AM = 5x + 4 and MB = 3+16 . Find the length of . AB
kirill115 [55]

Answer:

<h2>AB = 38</h2><h2 />

Step-by-step explanation:

|<----------------- AB ------------------->|

A--------------------M--------------------B

     5x + 4                      3+16

since M is at midpoint, AM = MB

5x + 4 = 3 + 16

5x = 3 + 16 - 4

x = 15 / 5

x = 3

AB = AM + MB

AB = 5(3) + 4 + 3 + 16

AB = 15 + 23

AB = 38
