What is the positive root of the equation ( x − 4)( x + 3) = 0?

x=4

Step-by-step explanation:

(x-4)(x+3)=0

The roots are x=4 and x=-3

The positive root: x=4

b. x- 48 =120

step-by-step explanation:

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
