Two numbers have a sum of 44. The larger number is 2 more than the smaller number. What is the smaller number?

17
21
23
19

The answer is 21.

Step-by-step explanation:

If the numbers have a distance of 2 on a number line then we can break 44 into two pieces , we now have two equal pieces equivalent to 22, we now add to one piece one and we subtract one from the other piece creating a gap of 2 between the two numbers while the sum of both is still 44.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

the first one, all those points on the line just make a strait line.
