12 x 2 = 24 (Julio), 24 x 4 = 96 (David).
The question is telling you that the length of the rectangle is 3 metres more than twice the width.
So let:
<em>w= width</em>
<em>L= length</em>
Because the length is 3 metres more than twice<em> </em>the width: <em>L= </em><em>2</em><em>w+</em><em>3</em>
They also tell you the perimeter is 48 metres.
<em>P= L+L+w+w</em>
So the equation of the perimeter is:
<em>48= (2w+3)+(2w+3)+2w +2w</em>
<em>48= 2(2w+3) + 4w</em>
To find w, expand and simplify.
<em>48= 4w+6+4w</em>
<em>48= 8w + 6</em>
<em>42= 8w</em>
<em>5.25=w</em>
Now that you know the width, plug in the value into the length equation:
<em>L= 2w+3</em>
<em>L=2(5.25)+3</em>
<em>L=10.50+3</em>
<em>L=13.5</em>
If I am wrong let me know! I hope this helps.
A)
2, 4, 6, 8, *10
The fifth row contains 10 cans.
----------------------------------------------------
b)
2+4+6+8+10+12+14+16+18+20=110
-----------------------------------------------------
c)
2*Row=Number Of Cans
When Row=1, Number Of Cans=2.
When Row=5, Number Of Cans=10.
When Row=10, Number Of Cans=20.
12-8 is 4 and 3/4 is 75% if that is what youre asking but specify
The answer is C
10% = 0.10
12 x 0.10 = 1.20
12 - 1.20 = 10.80
