Answer:
A] A function is a special type of relation for which there is a rule that pairs each input with exactly one output.
Step-by-step explanation:
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.
Answer:
2(5x-3y-1)
Step-by-step explanation:
perimeter of a rectangle formula:
2l+2w
l=length(2x-3y)5x
w=width(3x-1)
2(2x-3y)+2(3x-1)
4x-6y+6x-2
10x-6y-2
2) all of these numbers have a gcf of 2 so lets divide this equation by 2:
2(5x-3y-1)
hope this helps!
Answer:
m=3/4
Step-by-step explanation:
Answer:
13x
because you would comibne like terms, so you add the 8 and 5.
