1 A rectangular wall is divided into three sections. Each section is painted a different color. Red Green Blue • The section painted red is 7 feet wide and 4 feet tall. • The section painted blue is 7 feet wide and 3 feet tall. • The green section is a square. What is the area of the green section?​

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

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

the correct option is b
