Which value from the set {1, 2, 9, 20} will make 4(3 + x) = 6x + 4x true

2

Step-by-step explanation:

4(3+2) = 6(2)+4(2)

4(5) = 12 + 8

20=20

2

Step-by-step explanation:

4(3+2)=20

6(2)+4(2)

12+8=20

so 2 is the answer i hope this answer helps you and solve the question if you don't know please use calculaotor  this question you need to use substitution so substitute values from the set as x and try putting in to both equation to see both equation has same answer and matches  

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

x + 4/7
