20^2 = 16^2 +x^2
400= 256+ x^2
x^2 = 400 -256
x = 144^1/2
=12
b. yes

Remark
A cube has six sides, all of them equal. The formula for 1 side is s^2. The formula for all six = 6s^2.
Step One
Find the surface area of the larger cube.
Area = 6 *s^2
s = 15
Area = 6 *15^2
Area = 6 * 225
Area = 1350
Step Two
Find the area of the smaller cube
Area = 6s^2
Area = 6 * 12^2
Area = 6 * 144
Area = 864
Step Three
Find the difference
Area1 - Area2 = difference
1350 - 864 = 486
The difference is area = 486 units^2 <<<<< Answer
There is a slightly shorter way. Take out the common factor of 6
Difference = 6 * (15^2 - 12^2)
Difference = 6 * (225 - 144)
Difference = 6 * (81)
Difference = 486
Answer:
We conclude that the solution coordinates to the graphed system of equations will be:
Step-by-step explanation:
From the given graph it is clear that there are two lines:
It is clear that the red and blue lines meet or intersect at the point (1, -5). The point where the two lines meet is called the point of intersection.
In other words, the two lines meet at:
at x = 1, and y = -5
Thus, the point of intersection of two lines is:
We also know that the point of intersection of two lines is the solution of the system of equations.
Therefore, we conclude that the solution coordinates to the graphed system of equations will be:
