Find the area. Simplify your answer.

9514 1404 393

  x^2 +8x +12

Step-by-step explanation:

The area is the product of length and width. The product can be simplified using the distributive property.

  A = LW

  A = (x +6)(x +2) = x(x +2) +6(x +2)

  A = x^2 +2x +6x +12

  A = x^2 +8x +12

x^2+8x+12

Step-by-step explanation:

a= w * l

a= (x+6)*(x+2)

a= x^2+8x+12

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
