Answer:
4
Step-by-step explanation:
4 x 5= 20
4x6 = 24
So 4 can go in 20 and 24 making it the common factor
Answer:
11.4
Step-by-step explanation:
So we know that Triangle ACB is similar to Triangle EFD.
This means that their sides are proportional to each other.
We want to find x or side AB. To do so, we can set up a proportion.
The proportional side to AB is ED. Let's also use BC since we know its value. The proportional side to BC is DF. Thus:

Substitute x for AB, 3.8 for Ed, 15 for BC, and 5 for DF. Thus:

Reduce the right:

Cross multiply:

So, the value of x is 11.4
And we're done!
Answer:
3
Step-by-step explanation:
I think the coordinates are 1, 10 but not positive because if you graph it you can see a kite in it so make the point close to 4,10
