Answer:
42
Step-by-step explanation:
because that angle is a little less than half of 90 so 42 is the best answer
1. 7x + 3 - 2x....x = 8
7(8) + 3 - 2(8) = 56 + 3 - 16 = 43
4. 7 - (-2y) + y - 9....y = 6
7 - (-2(6) + 6 - 9 = 7 + 12 + 6 - 9 = 16
7. -x + 8 + 7x - (-1).....x = -10
-(-10) + 8 + 7(-10) + 1 = 10 + 8 - 70 + 1 = -51
10. 4x + 2y - x - 8....x = 1, y = 5
4(1) + 2(5) - 1 - 8 = 4 + 10 - 9 = 5
13. 2x + 5y - 3x + (-8y)....x = -9, y = 9
2(-9) + 5(9) - 3(-9) - 8(9) = -18 + 45 + 27 - 72 = -18

Answer
42.025
Step-by-step explanation:
8
90.425
- 48.400
= 42.025
You substitute the 9 to an 8

If the problem says "space", that usually means that they are talking about volume. The maximum length the box can be is 8.4 inches. To find volume, you do length * width * height. You know the length and height, as well as the volume. You can replace the width with "x". Your equation should be:
11.5 * 8.4 * x = 272.8
Then you can just solve for x by dividing both sides by (11.5 * 8.4). The answer should be about 2.82 inches.
