Which expression is equivalent to ?

Option 4 .

Step-by-step explanation:

We need to simplify out the given expression . The given expression is ,

Now see that the term ( x +5) is common in both numerator and denominator . Therefore we can cancel it out . The expression becomes ,

Now x⁴ and x can again be cancelled out in numerator and denominator . Similarly we can cancel 12 and 30 by 6 . We have ,

On looking at the provided options , 4th option is correct .

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
