Hey there :)

4t ( 2s - 7 )
We need to apply what is called the distributive property.

The student did a mistake by not distributing 4t to both values inside the bracket
The distributive property is used to get rid of the parenthesis/bracket

The student's answer should be:
4t ( 2s ) + 4t ( - 7 )
8st - 28t

The answers are C and E,
According to the interior and exterior angle theorem, this should be correct:
<3+<4+<6=180
<3+<1=180
<4+<6=<1
so they are the interior opposite of <1

1250 lbs of sand.

So first let's find the volume of the sand in the sandbox. You have a square sandbox, with a side length of 5, meaning you have a length and width of 5. You also have half a foot of sand in the sandbox, meaning that you have a height of 0.5. To find the volume of the sand, multiply the length by the width by the height:

$5 * 5 * .5 = 12.5$

So you have 12.5 cubic feet of sand. If each cubic foot of sand is 100 lbs, then you just multiply the two:

$12.5 * 100 = 1250.0

= x·[2(x²- 4x + 4) + 3(x² + 6x + 9) - x² + 5x]

= x(2x² - 8x + 8 + 3x² + 18x + 27 - x² + 5x)

= x(4x² + 15x + 35)
