Answer:

-30bc + 50bd

Step-by-step explanation:

3a + 5b/3c - 5d = 3a - 5b/3c - 5d

(3c - 5d)(3a - 5b) = (3a + 5b)(3c - 5d)

9ca - 15bc - 15da + 25db = 9ac - 15ad + 15bc - 25bd

9ca -15bc - 15da + 25db - 9ac + 15ad - 15bc + 25bd

9ca and -9ac and -15da and 15ad cancel each other out, so

-30bc + 50db is left

Osian was 1.5 m tall. In the last couple of years,his height has increased by 20%

3241004551 [841]

For this case we must find the current height of Osian. For this, we use the following rule of three:

1.5 m ----------------> 100%

x -----------------------> 120%

From here, we clear the value of x.

We have then:

$x = \frac {120} {100} (1.5)\\x = 1.8 m$

Answer:

The current height of Osian is given by:

$x = 1.8 m$
