Answer:
b; 1 real root and 2 imaginary roots
Step-by-step explanation:
From here, we have
x(x^2 + 121) = 0
x = 0 (1 real root)
or
x^2 + 121 = 0
x^2 = -121
x = √(-121) (2 imaginary roots)
so is would be two complex numbers from above
It’s 15, 21, 28 because it’s going up 1,2,3 etc and adding one each time it goes up
Answer:

Step-by-step explanation:
Answer:
X = 13 (rounded off to one decimal place)
STAY SAFE GOD BLESS YOU
Step-by-step explanation:
X² = H² - b²
X² = 23² - 19²
X² = 529 - 361
√x² = √168
X = 12.9614
X = 13 (rounded off to one decimal place)
