10,10 and 20 cannot as 10+10=20 so there would be a triangle with no area.
The others can all be the sides of a triangle as 7+7>8, 7+6>11 and 2+8>9.

I think the answer is 72, sorry if it is wrong
Answer:
6=-3/4x+(-4)
Step-by-step explanation:
The equation of any straight line, called a linear equation, can be written as: y= mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis. So for the given information you can see that they gave you your slope of -3/4 so you fill that in under the m. The point that would cross the y axis would be -4 because when you think of it on a graph you would see it as (-4 y) and (6 x). When you are writing linear equations you use the form y=mx+b.
Hope this helps
