Heidi solved the equation
3(x + 4) + 2 = 2 + 5(x – 4). Her steps are below:

whats her steps?

Step-by-step explanation:

x=16

The Steps to solving this equation:

3(x+4)+2=2+5(x-4)

multiply numbers in parenthesis by 3

multiply the other numbers in parenthesis by 5

3x+12+2=2+5x-20

subtract 2 to 2

3x+12=5x-20

move terms

3x-5x=-20-12

subtract 3x to 5x, and subtract -20 to -12 but since there both negatives the equation is addition.

-2x=-32

divide Both sides by -2

x=16

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

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.
