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:
Step-by-step explanation:0.04
Answer:
Point - Slope Form: (y - 3) = 0.4(x - 5)
Slope - Intercept Form: y = 0.4x + 1
Step-by-step explanation:
Well if it's parallel, they have the same slope
Slope = 0.4
I'll do it in two forms:
Point - Slope Form: (y - 3) = 0.4(x - 5)
Slope - Intercept Form: y = 0.4x + b
3 = 2 + b
b = 1
y = 0.4x + 1
I might be wrong
X intercept-(9,2/0)
y intercept-(0,-9)
hope this helps
bearing in mind that 9 months is not even a year, but since there are 12 months in a year, then 9 months is really 9/12 years.
