Step-by-step explanation:
It would go closer to the five on the number line. Hope this helps!
pi r squared, it doesnt let me type out the symbols sorry
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
First, distribute the right side.
8*(x + 5) = 8x + 40
Then, we write the whole equation:
8x + 47 = 8x + 40
Looking at it, we can subtract 8x from both sides, so that we're left with:
47 = 40
However, we obviously know that 47 is NOT equal to 40, so there is <em>no solution</em> for this equation.
