Since this is a right triangle, you can use the pythagorean theorem, 
, to find XY. Since we know that 15 and 17 are our legs and that XY is the hypotenuse, we can solve it as such:
In short, XY is √514, or 22.67 rounded to the hundreths, units long.

Answer:
No.
Step-by-step explanation:
No. 5 - 4.2 = 0.8
Answer:
(3, 9)
Step-by-step explanation:
Set 3x and 2x+3 equal to each other forming an equation in x.
3x=2x+3
Solve for x.
x=3
Substitute the given value of x into the equation y=3x.
y=3x3
Solve for y.
y=9
(x, y) = (3, 9)
Hope this helps :)
If 5 consecutive integers is 205,
then a + b + c + d + e = 205
but also, each integer is separated by a difference of 1
⇒ a + (a + 1) + (a + 2) + (a + 3) + (a + 4) = 205
⇒ 5a + 10 = 205
⇒ 5a = 195
⇒ a = 39
∴ third term = 39 + 2
= 41
