<em>ANSWER:</em>

<h2>7k</h2>

<em>STEP:</em>

Add -k and 8k. If you don't know why, since there is two "-". Two of those sign mean to add. And negative plus a positive is negative or positive. Or, you can just do 8k-1k. That is the same. You'll get 7k.

-k-(-8k)

= -k + 8k (two negatives equal one positive)

= 8k-k (flip it around because of the commutative property)

=7k (basic subtraction)

I really hope that helped :)

You are knitting a blanket. You want the area of the planet to be 24ft^2. You want the length of the blanket to be 2ft longer th
frosja888 [35]
The area of the blanket - 24 ft²
length being longer than the width means that blanket is a rectangle 
width of the blanket = x 
length of blanket = x +2
area = length * width 
area = x * (x+2)
        = x² + 2x
since area = 24
x² + 2x = 24
x² + 2x - 24 = 0
we have a quadratic equation and we need to now solve for x
x² + 6x - 4x - 24 = 0
x (x + 6) - 4(x + 6) = 0
(x-4) (x+6) = 0
x-4 = 0    or x + 6 = 0
x = 4      or x = -6
x could be either 4 or -6. since dimensions cannot have negative values,
x ≠ -6
therefore x = 4
width = 4 ft
length = 6 ft
