The first set of expressions bc 3x is equivalent to 3x and -7y is equivalent to -7y
Step 1: move all terms to one side
7 + 2x^2 - 10x = 0
Step 2: Use the quadratic formula
X = 10 + 2(square root of 11). 10-2 _/—-11

Step 3: Simplify solutions
X= 5 + (square root of 11) 5 - (square root 11)

Neither inscribed in the circle, nor circumscribed about it! 2 if the sides of the triangle are TANGENT to the circle, which means just touching at one point
Easier than it looks, all you have to do is first subtract 13 from 299. You should get 286. Then, you just divide this number by two to get 143. Finally, since it asks for ZENA'S average, you add the 13 back to 143 to get the final answer of the average number of pins Zena took down, which is 156!
