4(x+7)+3(2x-3) what is the answer to this

10x + 19

Step-by-step explanation:

Because we don't know what x equals, and theres no indication of what this expression equals, the most we can do is simplify.

First, use distributive property:

4x + 28 + 6x - 9

Next, add like terms: 4x and 6x are like terms, 28 and -9 are also like terms.

4x + 6x = 10x

28 + -9 = 19

10x + 19 is the simplest form we can go.

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.
