The question is incomplete, as the options to select the required condition from were not listed. So, I will answer on general terms
From the question, we understand that the cube has an open-top and the surface ares is 256 in^2
Let L represents the edge length, the surface area (S) is:
Substitute 256 for S
Divide both sides by 5
Take square roots of both sides:
---- approximated
The volume of the cube is:
<em>So, the edge length of the cube is 7.16 inches and the volume is 366.36 cubic inches</em>

Given:
Distance between two buildings = 
feet apart.
Distance between highway and one building = 
feet.
Distance between highway and second building = 
feet.
To find:
The standard form of the polynomial representing the width of the highway between the two building.
Solution:
We know that,
Width of the highway = Distance between two buildings - Distance of both buildings from highway.
Using the above formula, we get the polynomial for width (W) of the highway.
Combining like terms, we get
Therefore, the width point highway is 
.
One clock of any type costs $3.20. a clocks cost 3.2a. w clocks cost 3.2w.
Add 3.2a to 3.2w to find the total cost.
T = 3.2a + 3.2w
T = 3.2(a + w)
Both expressions above are correct answers.
Answer:
5 (x - 1) (4 x + 7)
Step-by-step explanation:
Factor the following:
20 x^2 + 15 x - 35
Factor 5 out of 20 x^2 + 15 x - 35:
5 (4 x^2 + 3 x - 7)
Factor the quadratic 4 x^2 + 3 x - 7. The coefficient of x^2 is 4 and the constant term is -7. The product of 4 and -7 is -28. The factors of -28 which sum to 3 are -4 and 7. So 4 x^2 + 3 x - 7 = 4 x^2 + 7 x - 4 x - 7 = 7 (x - 1) + 4 x (x - 1):
5 7 (x - 1) + 4 x (x - 1)
Factor x - 1 from 7 (x - 1) + 4 x (x - 1):
Answer: 5 (x - 1) (4 x + 7)
