Which statements are true about the unknown side length in this right triangle? Check all that apply. A triangle with side StartRoot 13 EndRoot meters and hypotenuse of 6 meters. The equation a squared + (StartRoot 13 EndRoot) squared = 6 squared can be used to find the unknown length. The equation (StartRoot 13 EndRoot) squared + b squared + 6 squared can be used to find the unknown length. The equation (StartRoot 13 EndRoot) squared + 6 squared = c squared can be used to find the unknown length. The length of the unknown leg is StartRoot 23 EndRoot meters. The length of the unknown leg is 7 meters.

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?

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.
