Answer:

Expand the 21(2-x)=42-21x

then you add 12 x with 42-21x

making it 42-9x=44

hence,

-9x= 2

9x= -2

x=  - 2/9

hope this helps.      :)

EXPLANATION:
21(2 - x) + 12x = 44
=> 42 - 2x + 12x = 44
=> 42 - 14x = 44
=> -14x = 44 - 42
=> x = 14/2
=> x = 7

ANSWER: x = 7

Hope it helps u!

The surface area of the cube is 54 square feet. What is the length, in feet, of one edge of the cube?​
Brut [27]

Answer:

3 ft

Step-by-step explanation:

A cube is made of 6 equal faces each of which is a square with the same side length. The surface area of the cube is the surface area of one side multiplied by 6. We know the surface area is 54 so divide this by 6.

54/6 = 9 ft^2

Since the surface must be a square, take the square root of 9 which is 3 ft. The length of one edge of the cube is 3 ft.

1,2,3,5,6,10,15,30 because by looking at the number at the ones place, when it is 0 or an odd number, it could be divided by 2. When the places are added together and when it is divisible by 3, it is the factor of 3. Also, when there are 2 and 3 as a factor, it is also divisible by 6.
