Simplify
6(2x + 1) = 2(5x + 2)
18

156x²

Step-by-step explanation:

6×2x=12x+1=13x

2×5x=10x+2=12x

you multiply those numbers together because if the is no sign like addition or subtraction its considered multiplication so you multiply 13x by 12x

and you will get: 156x²

cuz also is x is multiplied by x it turns into a power/index

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
