You can use photo math to help you,It helps a lot of people with equations. You should go ahead and give it a try
That equation tells us that (10 + x) = (3 + 4x). Can you handle it from there ?
Answer:
4.8 inches
Step-by-step explanation:
<em>See comment for complete question</em>
Represent the larger triangle with 1 and the smaller with 2.
So, we have:
-- height of 1
Required
Determine H2 --- Height of 2
To do this we apply dilation formula.

In this case:

Substitute 6 for H1 and 0.8 for Scale Factor


Hence, the height of the smaller triangle is 4.8 inches
The correct answer to your problem is B.
y-4 = 3(x-2)
