Answer:
24s^2, 54s^2, 96s^2
Step-by-step explanation:
Let s represent the initial side length of the cube. Then the area of each face of the cube is A = 6s^2 (recalling that the area of a square of side length s is s^2).
a) Now suppose we double the side length. The total area of the 6 faces of the cube will now be A = 6(2s)^2, or 24s^2 (a 24 times larger surface area),
b) tripled: A = 6(3s)^2 = 54x^2
c) quadrupled? A = 6(4s)^2 = 96s^2
Answer:
34cm
Step-by-step explanation:
To find the missing sides you have to see how much the bottom is, then the other sides so in the case the bottom is 10cm and top is 3cm on each side. and you want to find the middle. so you would do 10 - 3 - 3 = 4
When we eliminate y,(by adding here), resulting equation would be:
2x - 14 =0
So, x = 7
You can find the value of y as well, by substituting the value of x,
7 - y -8 = 0
y = -1
Hope this helps!
Answer 4
6 goes into 24 4 times and since both the top and bottom are negative the answer is positive
Example:15/5=1/3 so that's an example
