Help! This question is on mathswatch. Is is due in tomorrow and I need help. Please help. 10 points for helping me. Thanks

Step-by-step explanation:

split into 2 parts (2 rectangles)

area of first rectangle = 10 x 27 = 270cm^2

area of second rectangle = (24 - 10) x 9 = 126cm^2

total area = 270 + 126 = 396cm^2

it's 5 points not 10

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)
