Answer:
1)-n-5m
2)-13n+10m+6mn
Step-by-step explanation:
1) (6n-7n)-5m= -n-5m
2)(n-7n-7n)+(2m+2m+6m)+6mn= -13n+10m+6mn

Answer:
80 m.
Steps: perimeter =4 x side
=4x20=80m
Note:
1: tens
2: ones
.
1: tenths
5: hundredths
3: thousandths
7: ten-thousandths
You are solving for thousandths. Look at the number in the ten-thousandths place. It is a 7. Because 7 is greater than 5, you round up
12.1537 => 12.154
12.154 is your answer

Answer:
no
Step-by-step explanation:
The given lengths do not satisfy the Pythagorean theorem:
34² ≠ 33² +16²
1156 ≠ 1089 +256
The given sides do not form a right triangle.

<em>Alternate solution</em>
You can also compute 34² -33² = (34+33)(34-33) = 67·1 = 67 ≠ 16².
Even simpler, a Pythagorean triple will never have zero or two even numbers. The numbers (16, 33, 34) cannot be a Pythagorean triple.
