There are 109 pairs. Hoped this helps:)!
Y=-2/3x-2
Slope:-2/3
Slope intercept form is y=mx+b. So you have to isolate the y.
Subtract 2x from both sides
3y=-2x-6
Divide 3 from both sides
y=-2/3x-2
5/6 because there are 5 possible possibilities and 6 numbers on the dice I'm assuming that the dice has 6 faces.
The answer is C. Why? Because, they said the length is 10 feet longer. 260+10=270
so it's,
L=260 W=270
