I NEED HELP ASAP ILL MARK AS BRAINLIEST IF CORRECT!

A. $30.00

Step-by-step explanation:

1. Find the common difference, or by how much the value changes per pound.   Divide the price of the sales by the amount of pounds to find the rate. The rate must be $2.50 since 10 ÷ 4 = 2.5. To confirm, use 2 or 3 pairs of values. 15 ÷ 6 = 2.5, which confirms that the common difference is 2.5. This means that every pound of asparagus is $2.5.

2. Now that the rate is known, multiply it by 12. 2.5 * 12 = $30.00, which is the final answer.

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)

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
