Which of the following is an example of a quadratic equation? O A. x+10 = 33
O B. x2 - 64 = 0
O C. Y-776
O D. y = 4x + 6

B. x^2 - 64 = 0

Step-by-step explanation:

A. x+10 = 33  

B. x^2 - 64 = 0

C. Y-776

D. y = 4x + 6

A quadratic has an term with a power of two

b

step-by-step explanation:

b

d) 30 units^2

area of rectangle = l × b

= l × b

= 10 × 3

= 30 unit^2
