Which of following is an example of a quadratic inequality?

B

Step-by-step explanation:

Quadratic inequalities are inequalities involving quadratics.

A is not an inequality.

B is an inequality and we can rewrite B as:

So, B is a quadratic inequality, and is the answer.

C is not a quadratic. The x terms are not squared.

Likewise, D is not a quadratic either since no x terms are being squared.

answer: it is 1: 47 pm

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
