Step-by-step explanation:
Prove equality
Consider left and right parts separately.
<u>Left part:</u>
<u>Right part:</u>
Hence
Since left and right parts are the same, the equality is true.
Answer:
Area = 245 ft
(Width
Step-by-step explanation:
l = 5w
Where l is length and w is width.
We also know that the perimeter is 84 ft, so:
2l + 2w = 84
Now we can plug in 5w for l since we found the equality earlier:
2(5w) + 2w = 84
and then solve for w:
10w + 2w = 84
12w = 84
w = 7
so
l = 5 × 7
l = 35
The length is 35 and width is 7 so
the area of the rectangle is

Answer:
0, -2
Step-by-step explanation:
The solution of an ordered pair is when the two lines intersect on one of the boxes.
In this case, the two lines meet at <u>0,-2</u>
<u />
The x is 0
The y is -2
Supplementary understanding of why it is negative:
Since the x (horizontal line) hasn't moved anywhere from the middle, the origin or (middle line) represents zero, therefore since it HAS NOT moved, it shall remain zero.
Since the y (vertical line) meets at "two-down", down would indicate it is negative (below the origin), and it only went down two boxes, so that's where the two came from.
