A cube is made up of 6 squares
One square has 4 edges of equal length
The area of one face is Area = s^2

Answer: She would have to work 7 hours to earn $260.
Step-by-step explanation: 40×7=280 280-20=260 Hope this helps.
So let the smaller integer be 2x+1 and the larger one be 2x+3. So 2x+1+2x+3 is 32. Simplifying, we get 4x+4=32. So subtracting 2 from both sides we get 4x+2=30. So dividing by 2 we get 2x+1=15. So 2x+3 is 17. So the numbers are 15 and 17
The answer is 36. because 12x3=36, 9x4=36, and 4x9=36, so it is the least common denominator
