Chris: x + 3 (x + 3) - 2 = x + 1
Nathan: 18 (18) - 2 = 16
Jacob: x (x) - 2 = x - 2
Chris + Nathan + Jacob = sum
x + 1 + 16 + x - 2 = 59
2x - 15 = 59 <em>added like terms (x and x) and (1, 16, and -2)</em>
2x = 74 <em>added 15 to both sides</em>
x = 37 <em>divided both sides by 2</em>
Answer: Jacob is 37 yrs old

Answer:
(a) a squared + 15 squared = 17 squared
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides is equal to the square of the hypotenuse.
a^2 + 15^2 = 17^2 . . . . . . matches the first choice
Answer:
It isn't
Step-by-step explanation:
An x can't have to y's
way to remember: x=exes y=wives
you can have multiple exes (x's) but only one wife (y's)
0 has two y's
