This is a maybe. Im not sure if this is right but its what I got.
Answer: "possible" rational roots: ±1/5, ±3, ±1
Step-by-step explanation: Take plus or minus the factors of the constant divided by the factors of the leading coefficient.
In this case, the constant is 3, so the factors are 1 and 3, and the leading coefficient is 5, so the factors are 5 and 1.
1/5, 3/5, 1/1 and 3/1 are possibilities, simplify and attach the ± to each.
Answer:
9.2
Step-by-step explanation:
Since it is a right triangle, we can use pythagorean theorem to figure out the hypotenuse length.
a^2 + b^2 = c^2
6^2 + 7^2 = c^2
36 + 49 = c^2
c^2 = 85
square root both sides get
c= 9.219, rounded to nearest tenth is 9.2
