use common sense to determine whether the given event is possible.

a bag contains 10 red marbles and 3 blue marbles. susan picked two marbles from the bag without replacing them, and she chose 2 red marbles.

a)it is possible and likely.

b)it is impossible.

c)it is possible, but very unlikely.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

the correct is answer is a 9-sided polygon!
