Verify Answer:

Answer: square root(265)
Step-by-step explanation:
Again, you can solve this via the Pythagorean theorem(a^2+b^2=c^2)
a= a side
b= another side
c= hypotenuse
Now, Substitute
12^2+11^2=x^2
144+121= 265
Now, square root and you get
square root(265)
-5(-1-2)
5+10
15
Or
-5(-1-2)
-5(-3)
15
It's 15 either way.
Answer:
y = 3x + 2
Step-by-step explanation:
The shaded region is somewhat going up, and the graph is positive. That leaves 2 answer choices. If you measure the slope by counting the blocks from one point to another by counting up/down from one point to the height to another point, and then go right or left to the other point. the slope is 3, therefore y = 3x +2 is the answer, as it is the only one that the shaded region is above the line and that has a slope of 3. Hope this helps!
