Solve each equation if there is no solution write no solution if every number works write all real numbers. 1. 6x-16=14x+8

2. 9y+21=3y-5

3. 5n+7+3n=-8+3n

4. 6d-1=-d+ 20

5. 3b+8-5b= 2 (4-b)

6. -11 - 2p= 6p+5 (p+3)

7. 7w-3 (w+6) = 6w+ 14

8. 6(n+3)=2 (3n-9)

9. -(3b-15)=6 (2b+5)

10. h+3 (h-2)=2 (2h-3)

11. 5m+6-3m-9=4 (m-3)

12. 4(x-2)= 8 (x-3)- 12

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

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.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
