Answer:
-9m - 4 + 2m = -9 - 7m + 5
-7m - 4 = -7m - 4
-7m + 7m = -4 + 4
0 = 0
This is an identity solution because the same number equals the same number. That means there's an infinite set of solutions.
Answer:
875 ft^3
Step-by-step explanation:
Pick them apart starting at the bottom. The formul used is V=lwh
Starting at the bottom we have we have a sqare of 5 ft = 5ft^3= V = 125 ft^3
Then we have a rectangular prism: 5 x 5 x 20 = V = 500 ft^3
Third we have 5 x 5 x 10 = V = 250 ft3
125+500+250 = 875 ft^3

Answer:
z^(5/9).
Step-by-step explanation:
z^(8/9) / z^(3/9).
By the law of exponents:
= z^(8/9 - 3/9)
= z^(5/9) (answer).
