Jana and her friend bought 4 hamburgers, 3 orders of fries, and 2 milk shakes for $3 each. they paid for the food with $20. which part of the equation represents the total cost of their items? justify your answer. c = $20 - (4h + 3f + 6)

It should be (4h + 3f + 6) because that is the total of the hamburgers, fries, and shakes. The $20 is the bill they gave and when you subtract (4h +3f + 6) the result is the change the get back.

step-by-step explanation:

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.
