Assume the following: a + 2 = 3, b + 20 = 30, c + 200 = 300, d + 2,000 = 3,000, …. part 1 out of 3 solve each equation for each variable. a = b = c = d =

Step-by-step explanation:

a + 2 = 3a = 3 - 2a = 1

b + 20 = 30b = 30 - 20b = 10

c + 200 = 300c = 300 - 200c = 100

d + 2000 = 3000d = 3000 - 2000d = 1000

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

roots are from trees
