Answer:
13x^2 - 7x + 6
Step-by-step explanation:
(9x^2 -7x) - 1(-4x^2 + 6)
(9x^2 -7x) + 4x^2 +6
9x^2 - 7x + 4x^2 + 6
(9x^2 + 4x^2) - 7x + 6
13x^2 - 7x + 6
Answer:
6 7/8 minutes
Step-by-step explanation:
Say the entertainment segments are each x minutes long. Then, we have the equation:
x + x + 1 1/4 = 15
2x + 1 1/4 = 15
2x = 15 - 1 1/4
We need a common denominator. 1 1/4 = 5/4 and 15 = 60/4, so we now have:
60/4 - 5/4 = 55/4. Then: 2x = 55/4
Divide by 2 from both sides:
(55/4) / 2 = 55/8 = 6 7/8
Thus, each entertainment segment is 6 7/8 minutes long.

Answer:
The volume of cube-shaped block is 0.125 cubic feet.
Step-by-step explanation:
We are given the following in the question:
Edge length of storage container =

Edge length of block =

Putting value we get,
Edge length of block =

Volume of cube-shaped block = Volume of cube

Thus, the volume of cube-shaped block is 0.125 cubic feet.
10 percent of 11.50 is 1.15. Subtract that from 11.50 and you would get 10.35. The sale price would be $10.35
