Answer:
substitute the given values for m, n, and p into each problem and solve. Make sure you don't ignore minuses and negatives. Separate with parentheses to make sure you don't get confused.
Step-by-step explanation:
54: -7(-5) - 10( 3/2)
35 - 10(1.5)
35 - 15
20
55. -3mnp
-3 x (-5) x 3/2 x (-8)
15 x 1.5 x (-8)
22.5 x (-8)
-180
56. 8n / (-6p)
8(1.5) / (-6 x -8)
12 / 48
1/4 or .25
57. p squared is (-8)(-8)
2(-8)(-8)(-1.5) / (-5)
128 (-1.5) / (-5)
-192/ (-5) negatives cancel out
192/5
38.4
Ok so the answer is 8 + 21xy + 8y
