(one triangle on a graph has a vertical side of 3 and a horizontal side of 4. another triangle on a graph has a vertical side of 9 and a horizontal side of 12. could the hypotenuses of these two triangles lie along the same line? no, because they need to be the same size no, because they are not similar triangles yes, because they are similar triangles yes, because all triangles can fit along this line

Yes because they are similar triangles.

Step-by-step explanation:

The corresponding sides are in the same ratio:

3/9 = 4/12  and there is a right angle between the 2 pairs of sides so the triangles are similar.

The third choice is the correct one.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

the image of (6, 9) under a dilation is (4, 6). the scale factor is
