Yes they do. In order to do this you must make the fraction 70/2 and 105/3. If you divided each one of those you get 35 for both which means it's a proportion.

Help how do i find the missing height of a parallelogram
WINSTONCH [101]

Answer:

To find the missing base, you simply divided the area by the given height. This will work the same way if you are looking for the height. To find the missing height, divide the area by the given base.

Step-by-step explanation:

base = 35cm, height = ? cm, and a = 700 cm^2 a = bh

700 = 35 x h

700/35 = 35 x h/35

20 = h

Therefore, the answer would be 20cm. Hope this helps! :)

Plz help!! <br> If DF = 170, find the value of x. Then find DE and EF.
Firlakuza [10]

Answer

  • DE= 3x + 20 = 86

Step-by-step explanation:

DE: 3x + 20

EF: 2x + 40

DE+ EF= DF

3x+20 +2x + 40 = 170

5x + 60 =170

5x= 110

x= 22
