Hello,
5i or -5i since there would be at least 4 roots
Answer B and E
It's x=-5. It is a vertical line, and vertical lines have a consistent x coordinate. Since it passes through (-5,0), you take the x-coordinate of this point.
Answer: The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
Step-by-step explanation:
you don't list any expressions to choose from but
if width = x
and length = 2x
Area = 2x * x
Area = 2x^2
