Answer:
1/4, or 4 times smaller
Step-by-step explanation:
Since the surface area of a cube is just the combination of the area of all of the square sides, and the formula for those is s^2, if the side length was decreased by 1/2 then the surface area would decrease by (1/2)^2=1/4. Hope this helps!
Answer: Jenny
Step-by-step explanation:
By subtitue Y = 0
0=(x-3)^2
And you get 3
First, simplify out the brackets:
-20 - 4n = -12
Then, combine like terms by moving the -20 to the other side
-4n = -12 + 20
-4n = 8
Divide by -4 on both sides to isolate the n
n = 8/-4
n = -2
Well
if it is marked 1/3 off, then you're actually paying 2/3 of it.
2/3 of 123. " of " means multiply
2/3 * 123 = 246/3 = 82 So it now costs $ 82
