What is the solution to the equation below? Round your answer to two decimal places. 6+7*log_2 x=21

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

the answer would be 0.54

the answer is a) a healthy economy because it results from a steady rise in demand.
