I can’t see the picture☹️☹️☹️
Answer: The answer is D. Hope this helps :)
Step-by-step explanation:
2(7) + 4(-1) = 10
_2(7) + (-1) = -15
Y=1 and x=7 because if you make the first equation into a x= equation, you can just substitute it for the second equation and solve it.
Answer:
375000 ft^2
Step-by-step explanation:
From the statement that we have that it would be 1 time the length and 2 times the width because one side is not necessary and also we must take into account that it would be divided by 3 equal enclosures therefore we will use 1000 feet (3000/3) so Therefore, the perimeter would be equal to:
1000 = l + 2 * w
we solve for w:
l = 1000 - 2 * w
Also the area is equal to:
A = w * l
replacing:
A = w * (1000 - 2 * w)
A = 1000 * w - 2 * w ^ 2
We derive:
A '= 1000 - 4 * w
Let's equal 0:
1000 - 4 * w = 0
w = 1000/4
w = 250
replacing and we calculate l:
l = 1000 - 2 * 250
l = 500
A = 250 * 500
A = 15,000 ft ^ 2
Which means that for each subdivision the maximum area would be 125000 square feet and the total would be:
125000 * 3 = 375000 ft ^ 2
To find the number of paperclips, divide 56 by 7/8 to give 64. Multiply this by 0.03 to give a total cost of $1.92
