Determine which expressions, if any, are equivalent. Show your work. 4(x - 3)
6x - 2(x - 3)
x + 3(x - 2) - 6

4(x - 3) and x + 3(x-2) - 6 are equivalent.

Step-by-step explanation:

4(x - 3)  = 4x - 12

6x - 2(x - 3)  = 6x - 2x + 6 = 4x + 6

x + 3(x - 2) - 6 = x + 3x - 6 - 6 = 4x - 12

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

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
