What is the solution to the linear equation? 6k + 10.5 = 3k + 12 k = 0.5 k = 2 k = 7.3 k = 9

The value of k is 0.5

A is correct

Step-by-step explanation:

Given: 6k + 10.5 = 3k + 12

To solve: k

6k + 10.5 = 3k + 12

Subtract 3k and 10.5 both sides

6k - 3k + 10.5 - 10.5 = 3k - 3k + 12 - 10.5                  (Combine the like terms)

      3k = 1.5                                                                ( Divide by 3)

        k = 0.5                          

Hence, The value of k is 0.5

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
