Let x^2+50=0
solve for x first.
x^2=-50
x=+-√-50
Write that as a complex number
x=+-√50i
x=√50i or x=-√50i
Hope I helped :)

Step-by-step explanation:
Answer:
4(3x-10)
Step-by-step explanation:
12x-40 = (4*3)x-(4*10) = 4(3x-10). The GCF is 4.


An airplane is flying at a height of 5 kilometers above the ground. The distance along the ground from the airplane to the airport is 7 kilometers. What is the angle of depression from the airplane to the airport? (Write the answer to the nearest degree.)


✞ Step 1 ✞: Identify what is asked in the problem.
❒ The angle of depression from the airplane to the airport.
✞ Step 2 ✞: Use appropriate trigonometric ratio to solve the problem.
❒ Since the two legs of the right triangle are part of the problem, hence we use tangent ratio:

✞ Step 3 ✞: Solution and interpretation.





Hence, the angle of depression from the airplane to the airport is approximately 36°.
