It is possible to determine whether two triangles are similar if the lengths of all the sides are known. true or false?

  TRUE

Step-by-step explanation:

The triangles will be similar if corresponding side lengths have the same ratio. If you know all the side lengths, this is something you can determine.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
