An algebra tile configuration. only the product spot is shown. 8 tiles are in the product spot in 3 columns with 3 rows. first row: 1 + x squared, 2 + x. second row: 1 +x, 2 +. third row: 1 +x, 1 +. how many more unit tiles need to be added to the expression x2+4x+3 in order to form a perfect square trinomial? 1 2 3 4

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

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
