Answer: I think possible answers D
Step-by-step explanation:
Answer:
Both of them are correct.
The perimeter is found by adding up all four sides. If you notice, one of them is width and one of them is length. A rectangle has four sides, two width and two length.
l= length and w=width so P=2l+2w.
But, we can combine them by factorizing 2l+2w.
Lets see what we can pull out. We can only pull out 2.
2(l+w)=2l+2w.
2(l+w)=P
Both of them are correct.
Hope this helps plz hit the crown :D
Answer:
80
Step-by-step explanation:
<u><em>A = Area of First Rectangle </em></u>
<u><em>B = Area of Second Rectangle </em></u>
<u><em>w = Width</em></u>
<u></u>
12(w)=320+B (1st Equation)
8(w) = B (2nd Equation)
w=B/8 <em><u>(Plug this value of w into the first equation)</u></em>
12B/8 = 320 +B <u><em>(you get this)</em></u>
12B= 2560 + 8B <u><em>(Simplify)</em></u>
4B = 2560
B =640 <em><u>plug this value into the 2nd equation</u></em>
8(w) = 640
w = 80
<em>To Test This</em>
12x80 = 960
8x80 = 640
<h3>960 - 640 = 320
<u><em>Therefore the answer is correct the width is 80</em></u></h3>

The reduction expressed as a fraction of the original price is
80.00/249.99 ≈ 0.3200128 = 32.00128/100 = 32.00128%
The reduction in price was about 32%.
