Is the triangle a right triangle? Why or why not? A right triangle with sides labeled 7 miles, 12 miles, and 14 miles.

No, because 7^2+12^2=14^2.

No, because 7^2+12^2≠14^2.

Yes, because 7^2+12^2=14^2.

Yes, because 7^2+12^2≠14^2.

Investigate The Pythagorean Theorem
Please explain!

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
