Need po asap thank you

1. 16, 19, 21

2. 81, 243, 729,

3. 25, 31

4. 20/24, 19/24

5. 37

Step-by-step explanation:

1. The numbers are going up by +3 ( 1 + 3 = 4,     4 + 3 = 7 etc..)

2. The numbers are being multiplied by 3 ( 3 x 3 = 9,      9 x 3 = 27 etc..)

3. Numbers are going up by +2

4. Numbers are decreasing by 1/24 ( 23/24 - 1/24 = 22/24 etc..)

5.

12 - 7 = 5

22 - 12 = 10 (5*2)

82 - 57 = 25 (5*5)

We can see a pattern here and the pattern is that the numbers are increasing according to the x5.

Hence 22 + (5*3) = 37

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
