Description: They didn't distribute the 3 to both x and 5, so they just had 3x+5.
actual problem:
3(x+5)=3x+15
3x+15=3x+15
subtract 3x from both sides and end up with
15=15
Correct Answer: 15=15
Its same as powers of a whole number.
Lets take example
(1/2)²=1/2×1/2=1/4
We can write it in a different way (0.5)²=0.5×0.5=0.25
The volume formula is area of base×height. In this case, we are working with rectangles, so the formula is l×w×h. We have to find the volume of each block and add them together. Top rectangle: 12×30×4=1440. Middle rectangle: 30×36×4=4320. Bottom rectangle: 30×60×4=7200. 7200+4320+1440=12960 inches squared.
The factors are the following : 1, 2, 4, 7, 14, 28.
N> 8
Any value greater than 8 will work for n you choose
And this is why
48 < 6n
same thing as
6n > 48
divide by 6 on both sides
And that leaves you with
n>8
Examples which would work
n=9, n=120, n=756, n = 12
