Use the X-intercept method to find all real solutions of the equation. 23-7x + 7x + 15 – 0 a. X=-1, 3, or -- 5 2--1, 3, or 5 b. 4-1. – 3. or - 5 d. 1 = 1, -3, or 5

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
