The answer would be -0.5 hope this helped!
Answer is A, basically using the Pythagorean theorem but in a slightly different way, should still get you the same answer.
Answer:
The problem is stated as:
Min C = 15*(2*x +y) + 21*y
subject to x*y = 450
Step-by-step explanation:
Given that the region is rectangular, it has two opposite sides called x and two other opposite sides called y (both measured in feet). Then, the area (in square feet) is:
A = x*y = 450
One of the sides called y costs $21 per linear foot. The other 3 sides (two x and one y) costs $15 per linear foot. Then, the cost function is:
C = 15*(2*x +y) + 21*y
Answer:Identity Property
Step-by-step explanation:
If you are given a equation like this:
5+__=35 you can us 35 and subtract 5 to figure out the answer
30
<u>- 5</u>
30
which is 30.This could also be shown as the Identity Property.
