Use the expression below to answer parts (a) and (b). 4x – 3(x – 2y) +(6x – 8y)

a.
Write an equivalent expression in standard form, and collect like terms.

b. Express the answer from part (a) as an equivalent expression in factored form

5x-3x+6y+3x-4y=5x+2y. First, you need to count it, then draw x line and y line, that’s done!

Step-by-step explanation:

answer for #1 is c

answer for #2 is d

can i get brainliest

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.
