Answer:
( - 5,2);( -2, -3); (4, -1)
So your answer is: A.
Answer:
Answer: 216 cm2 (square centimetres
, in your question you had to put cm3, cubic centimetres, it's IMPORTANT )
Step-by-step explanation:
A perfect cube by definition has 3 equal dimensions, as an immediate rule: volume and total surface are equal, only the unit of measure changes (cubic for the volume, square for surface).
But let's calculate it anyway:
Volume = Edge * Edge * Edge = length * width * depth =
(remember: all edges are equal in this case)
so Edge = ![\sqrt[3]{Volume}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7BVolume%7D)
in your example Edge =
= 6cm
So the surface of one side is 6*6 = 36
There are 6 sides in total, so the total surface is 6*36 = 216 
Note: I call them "edges" but in case of a cube most say just "length"

Step-by-step explanation:
Answer:
x ≤ 17
Step-by-step explanation:
This is the same as solving an equation, except instead of and equal sign it's an arrow.
We have to evaluate everything in the parenthesis first.
3x - 2 (x + 1) ≤ 15
3x - 2x - 2 ≤ 15
Next, we combine like terms - x's
3x - 2x - 2 ≤ 15
x - 2 ≤ 15
Combine like terms - constants (add 2 to both sides)
x - 2 ≤ 15
<u>x ≤ 17</u>
18. all you have to to is take twenty and subtract 2 from it and you get x
