Which trinomials are perfect square trinomials? select each correct answer. a. y2+20y+100 b. y2+25y+200 c. y2+6y+36 d. y2+18y+81

Option A :

Option D:

Step-by-step explanation:

To Find: Which trinomials are perfect square trinomials?

option A :

Factorizing:

Hence Option A is perfect square

Option B :

Since this cannot be factorized

Hence not a perfect square

Option C:

Since this cannot be factorized

Hence not a perfect square

Option D:

Hence Option D is a perfect square

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24
