Pls tell the answers whoever gives the correct answer will be marked as brainliest

(D)

Step-by-step explanation:

Area (shaded) = Area (large rectangle) - Area (small rectangle)

= (4x + 3)(4x - 3) - (8x + 9)(2x - 1)

= 16x² - 9 - [16x² + 18x - 8x - 9]

= -10x

The correct option is (D)

i think 1: 2

step-by-step explanation:

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)
