Answer:
no
Step-by-step explanation:
We can use the Pythagorean theorem to check
a^2 +b^2 = c^2
11^2+13^2 = 17^2
121+169 =289
410 does not equal 289
This is not a right triangle
Answer:
The roots of the function are x = -5/3 and 3. Select these.
Step-by-step explanation:
The roots of the function are the solutions to the function. They are also called the x-intercepts or zeros. To find them, factor the function completely and solve using the zero product property.
f(x) = (3x+5)(x2-6x+9)2 becomes f(x) = (3x+5)(x-3)^2
Set each factor equal to 0 and solve for x.
(3x+5)=0
3x = -5
x = -5/3
(x-3)^2 = 0
x - 3=0
x = 3
