Determine the x-intercepts, the vertex, and the y-intercept. 12. s(x)= - (x - 1) (x - 3)
x-intercepts: and
vertex: ( , )
y-intercept:

there 3x and 4y hope this makes sense ik on a rush

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

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
