Width = 9cm
Length = 18cm
<u>Explanation:</u>
Let width = b,
So, length = 2b
Perimeter of rectangle = 2x(length + width)
According to the question,

Hence,
Width = 9cm
Length = 18cm
The answer is d) 14. Attached is a screenshot of how to do this on a graph. Graph the given point (5,12). Count out your slope on either side until you reach your given y value (6).
<span>(-2,7)
(18,1)
Slope = difference in "y" / </span><span>difference in "x"
Slope = 7 - 1 / -2 -18
</span>
<span>Slope = -6 / -20
Answer is 2) -3 / 10
</span>
*You could use a calculator
50 times 50 times 50 times 20 equals <span>2500000</span>
Your answer is <em>2500000</em>
since the equation on the left can be rewritten :
to be 5n-10 then both sides of the equation are equal
so any real number will work
