The answer would be 13. You just replace the "x" with "-2" so the equation will look like f(-2) = 2(-2)^2+5. Which all comes out to 13.

What is the value of x? Please provide an explanation, thanks!
Novosadov [1.4K]

Answer:

28

Step-by-step explanation:

What you do is add up 42 and 76, then you subtract that from 180, because all triangles add up to 180. the subtracted amount is what z equals. Then since its a straight line you know it adds up to 180. You add z (62) and 90 because its a right angle. then you subtract 180 by 152 to get 28.
