mind you that it has two complex roots, or imaginary values.
Answer:
32
Step-by-step explanation:
Pythagorean theorem
a = perpendicular
b = base
c = hypotenuse
we have to find the hypotenuse
so,
In mass or percent weight (%w); the concentration would be :
100 * 50 / (50 + 30) = 100 * 50/80 = 62.5 %w
Okay. The question is m/9 - 17 = 21. First off, we will add 17 to both sides. -17 + 17 cancels out. 21 + 17 is 38. That leaves m/9 = 38. Multiply each side by 9 to isolate the m, because m is the numerator and 9 is the denominator. m/9 * 9/1 cancels out. 38 * 9 is 342. Let's check this. 342/9 is 38. 38 - 17 is 21. 21 = 21. There. x = 342.
