Step-by-step explanation:
1x20=20
2x10=20
4x5=20
In order to have the least amount of each, you would need to purchase 2 packages of large plates. Here is the reasoning:
You can buy the following number of large plates and small plates:
Small: 8, 16, 24, 32, ...
Large: 12, 24, 36, ...
The smallest number that can be bought so you have an equal amount is 24 of each.
To get 24 large plates, you would need 2 packages.
20 inches... the area of the small window is 20^2 which is equal to 400. Therefore the bigger window is 25 inches long and the area of the bigger window is 625 inches^2. Add these areas together to get 1025 in^2

Answer:
84 in
Step-by-step explanation:
The Pythagorean theorem is used to find the length 'b'.
b^2 +12^2 = 37^2
b = √(37^2 -12^2) = √1225 = 35
Then the perimeter is the sum of side lengths:
P = a + b + c = 12 + 35 + 37
P = 84 . . . inches
Answer:
x = -12
Step-by-step explanation:
Let x be the number.
The product of 5 and x increased by 9 is equal to 15 less than 3 times x.
5x + 9 = 3x - 15.
We can isolate x, getting (5-3)x = -15-9
Then we can solve:
2x = -24
x = -12.
