Answer:
-4x(x +3)
Step-by-step explanation:
Factor out common factors from both terms.
Divide -4 & x from both terms.
(-4x²)/(-4x) = x
(-12x)/(-4x) = 3
x + 3 is the remainder, so keep together.
-4x(x + 3) is your answer

Maximum of area is when both length and width are equal
144/4=36 max area=36*36=1296
minimum of area is when width is 1 and length is half of<span> perimeter -1
</span> 144/2=72 72-1= 71 min area=71*1=71
1296-71=1225

Answer:
1.5 meters
Step-by-step explanation:
We know that the sum of all of the data in a set = average * number of data.
Therefore, the sum of the first 10 is 1.5 * 10 = 15 meters, the sum of the second 10 is 1.48 * 10 = 14.8 meters and the sum of the last 2 is 1.6 * 2 = 3.2 meters for a total of 15 + 14.8 + 3.2 = 33 meters. This means that the mean is 33 / 22 = 1.5 meters.
