Answer:
Zero
Step-by-step explanation:
any absolute value bars come off so -6+6=0
129 degrees you just add DCE and ECF together
Supplementary angles add up to 180 degrees more than the other, you can formulate an equation 180=(100+x)+x80=2x so, x=40 the other angle is 100 degrees more. So, the angle lengths are 40 and 140 degrees.
Answer:
7x³y² - 3x²y² + xy - 5
Step-by-step explanation:
Add like terms.
5x³y² + 2x³y² = 7x³y²
-3x²y² = -3x²y²
-3xy + 4xy = xy
2 - 7 = -5
Put them all together.
7x³y² - 3x²y² + xy - 5
1,038/12= 86.5833333 86x12=1,032
1,039-1,032=7 left over So you’ll need 87 boxes
