What describes the number and type of the roots of the equation 4x+7=0

a. 1 imaginary root

b. 1 real root and 1 imaginary root

c. 2 real roots

d. 1 real root

D : One Real Root

Step-by-step explanation:

Isolate "4x" by subtracting 7 from both sides.

So we get

4x = - 7

Then we divide each side by 4 to get - 7/4

x = - 7/4 so there is only one real root.
