Answer:
explain this question more clearer pls
Step-by-step explanation:
4x3=12
6+6=12
These are two ways to get 12
Answer:
12 inches by 12 inches = 15 dollars
48 inches by 48 inches = 80 dollars
Step-by-step explanation:
12 inches = 1 ft
so 12 inch by 12 inches is 1 ft * 1 ft
1 ft* 1 ft
1 ft^2
This is smaller than 3 ft^2 so they will get charged for 3 ft^2
3 ft^2 = 3 ft^2 * $5 / ft^2 = 15 dollars
48 inches = 48/12 = 4 ft
4ft * 4 ft = 16 ft^2
16 ft^2 = 16 ft^2 * $5 / ft^2 = 80 dollars
(3n-2m) (3n-2m)
(you multiply the first number (3n) by the first number in the 2nd bracket (3n) and then by the second number in the 2nd bracket (-2m)), and you do the same for -2m
9n2 - 6mn -6nm +4m2
9n2 -12mn + 4m2
