Answer:
-2
Step-by-step explanation:
Simplify the following:
2 - 3 - 4 - 4 + 7
2 - 3 - 4 - 4 + 7 = (2 + 7) - (3 + 4 + 4):
(2 + 7) - (3 + 4 + 4)
2 + 7 = 9:
9 - (3 + 4 + 4)
3 + 4 = 7:
9 - (7 + 4)
7 + 4 = 11:
9 - 11
9 - 11 = -2:
Answer: -2
27=3³ and 512=8³
(3x+8y)(9x²-24xy+84y²) are the two factors.
C is the answer.
8x3 is 24, 3x5 is 15, 8x5 is 40, 24 + 15 + 40 is 79 79x2 is 158
Answer:
subtract from both sides and then multiplying both sides

how can you solve y = -2x + 25 by subtraction
Answer:
0.07%
Step-by-step explanation:
This equation is solving for what percentage of 100 kg is 0.07 kg.
