Expand 2(b + 6 ) can somone please tell me the anwnser

(a−2b)6

Step-by-step explanation:

Use the Binomial Theorem. a6+6a5(−2b)+15a4(−2b)2+20a3(−2b)3+15a2(−2b)4+6a(−2b)5+(−2b)6

2b+12

Step-by-step explanation:

Because the number is in front of the bracket you have to times everything in the bracket by the number on the outside.

So,

2 times b is 2b

And

2 times 6 is 12

So it would be 2b+12

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
