I think its:

2(2x-3y)-3(x-2y-4)4

4x-6y-3x-6y(4)

Answer: 350/12

I think 29 2/12 can be also true because they didn't simplify the 2/12 to 1/6.

Step-by-step explanation:

You'll have to use the basic formula for volume is length × width × height. The sample box has the area of 23 1/3 which is found by length x width. They give you the height 1 1/4. I am assuming you will need to multiply 23 1/3 by 1 1/4. You'll get 350/12.

If it's simplify further it will be 175/6 or 29 1/6 as a mixed fraction.

Help with question 2
Ne4ueva [31]

Answer:

x = 97

Step-by-step explanation:

Question 2:

Recall that, the sum of all 4 angles in a quadrilateral = 360°.

This means that all the interior angles of the quadrilateral given above would sum up to 360°.

To find the value of x, create an equation by adding all the interior angles and set the sum equal to 360°.

Thus:

(x + 10) + x + 59 + x = 360°

Add like terms

3x + 69 = 360

3x + 69 - 69 = 360 - 69

3x = 291

3x/3 = 291/3

x = 97
