HELP FAST The diagram represents the process of creating a scale drawing from an original using a scale factor of 0.4. The base of the original drawing must be:

18 or B

Step-by-step explanation:

So we know that...

25.6 x 0.4 = 10.24

and

10.24 ÷ 0.4 = 25.6

So, if we are trying to find the base of the first triangle we would do

7.2 ÷ 0.4 = base

7.2 ÷ 0.4 = 18

BASE = 18

Hope this Helps!

D. 4

Step by step explanation:

It is d.4 I am pretty sure because the 4 is near the 2. It could also possibly be 3 though too.
