Answer:

D

Step-by-step explanation:

it cant be A or B becuase +7 × +7 = +49, -7 × -7 = +49. not all numbers will be squared and = -49

so it must be D

Answer:

d

Step-by-step explanation:

y² = - 49 ( take the square root of both sides )

y = ± [tex]\sqrt{-49}[/tex]

The [tex]\sqrt{-49}[/tex] is complex, then

no real values will make the equation true
