How do you find the scale factor of two triangles, 0.3 and 2.4?

1 answer:

8 0

Divide the larger one by the smaller one. 2.4 divided by 0.3 gives you 8. That means the scale factor is 8, or the larger triangle is 8 times larger than the smaller. We can prove this by multiplying 0.3 by 8 and getting 2.4

You subtract 16 from each side of the equation.
Then it will say exactly what number 'n' is.
_______________________________________

The equation is n + 16 = 9

On the left side, you subtract 16 from (n + 16) and you have 'n'.

On the right side, you subtract 16 from 9 and you have -7 .

Now the equation says n = -7
