Find the hypotenuse.*
2 cm
8 cm

square root of 68, or 8.24

Step-by-step explanation:

You have to use the Pythagorean theorem. 2 and 8 will both be squared. 2 squared is 4, and 8 squared is 64. Add those up and you get 68. Since the Pythagorean theorem states that a squared + b squared = c squared, you have to square C.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
