Formula for the rectangle area is a * b, In this case we know that:
a * b = 180
a (width) = unknown
b (length) = 1 1/4a
We can write it down as:
a * 1 1/4 * a = 180
a² * 1 1/4 = 180 / ÷ 1 1/4 (both sides)
a² = 144 / square root (both sides)
a = 12
Doublecheck:
a = 12
b = 1 1/4 * 12 = 15
a * b = 12 * 15 = 180 (so it's correct)
Answer: The dimensions of the painting are <u>12 x 15 inches</u>.
Answer: simplified expression is 3x+5
Explanation:
3(x+3)-4
-Distribute (multiply) 3 through parentheses to get
3x+9-4
-subtract the 9 and 4 to get
3x+5
That’s your solution to a simplified equation!!
So you have 12 cases delivered in 1 hour and 30 minutes. 30 minutes is half of an hour or .5
so 12/1.5 is 8, that is 8 cases per hour for a total of 32 cases in 4 hours.
