Answer:
Step-by-step explanation:
For example, a sum of a number and 6 is 12.
The number is unknown.
Let the number be x.
We can solve for x (unknown number). Subtract 6 from both sides of the equation.
The shortest height at which the two stacks will be same is 72 inches.
Step-by-step explanation:
Given,
Boxes that are 18 inches tall are being stacked next to boxes that are 24 inches tall.
It means that we will find least common factor of both the boxes;
18 = 2*3*3
24 = 2*2*2*3
LCM = 2*2*2*3*3 = 72
The least common multiple of 18 and 24 is 72, therefore,
The shortest height at which the two stacks will be same is 72 inches.

The perimeter of RSTU can be calculated alone without the help of MNPQ. It would be just 2(4) + 2(3) = 14 units. However, it would be much sensible if you want to find the parameter of the bigger rectangle. Since they are similar, you could use ratio and proportion.
(length/width)∨MNPQ = (length/width)∨RSTU
(x/9) = (3/4)
x = 6.75 units
Thus the perimeter of MNPQ is 2(6.75) + 2(9) = 31.5 units

Answer:
24;120;201600
Step-by-step explanation:
25. 3 salads, 4 main courses, 2 vegetables, 1 dessert
3*4*2*1=24
26. 5*4*3*2*1=120
27. 8*7*6*5*5*4*3*2*1= 201600
