236.715 ft squared

Step-by-step explanation:

This figure is composed of a rectangle and two semicircles that we can just combine into one circle. Let's find the areas separately.

Circle: the two semicircles will just add up to a circle, so we'll find the area of a circle with radius 15/2 ft.

≈ ft squared

Rectangle: the area of a rectangle is length times width; here the length is 15 and the width is 4, so A = 15 * 4 = 60 ft squared.

Now, we just add these two together:

176.715 + 60 = 236.715 ft squared

Hope this helps!

236.625

Step-by-step explanation:

2 semi circles = 1 circle

Radius = 15/2 = 7.5

Circle + Rectangle

(3.14 × 7.5²) + (15 × 4)

236.625 ft²

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)
