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:
I may not be correct, depending on what you were taught, but it would be...
17/30
Step-by-step explanation:
(2/5×6/6)+(1/6×5/5)
12/30 + 5/30
17/30
keep in mind you don't add the denominators at all ( the numbers at the bottom half of the fraction)
None of the above because j+j+2k will give you 2j+2k and 2(j+j+k) will come out as 2j+2j+2k Hope this helps!
(x + x - 14) + 7 = 85
2x - 7 = 85
2x = 92
x = 46
One number is 46, and the other is 32.
Answer:
B) 200 miles.
Step-by-step explanation:
Let M = miles that you need to drive
45 + 0.295M = 90 + 0.07M
90 - 45 = 0.295M - 0.07M
45 = 0.225M
M = 45/0.225
M = 200
Hope this helped :)
