Which expression is equivalent to (6x3 – 5.02 – 6) + (3x2 + 10 – 9x')? o 923 – 4x2 + 4
0-313 - 2x2 +4
0 -32+ 8x2 - 4
O 1473 +872 +16

b) 36

step-by-step explanation:

18 times 2 is 36

what graph

step-by-step explanation:

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
