D. (y-3)
I'm assuming that they want you to find the factors of the quadratic expression, which are (y-5)(y-3). (y-5) isn't up there, so (y-3) is the only solution that's really possible.
It's the first one because at Jefferson middle there are 24 students to 1 teacher and all you know about Hamilton middle is 12 teachers to 312 students
24•12= 288
So Jefferson will have 12 teachers for 288 students
Using similar triangles, the proportionality ratio of △QRS to △KJI is of 1/3.
<h3>What are similar triangles?</h3>
Similar triangles are triangles that have the same angles, and whose side lengths are proportional.
For this problem, we have that:
- The sides that have length of 2 on △QRS have lengths of 6 on △KJI.
- The side that has a length of 1 on △QRS has length of 3 on △KJI.
Hence the proportionality ratio of △QRS to △KJI is given as follows:
2/6 = 1/3.
