Answer:
(2x+1)(x+3)
2x(x+3)+1(x+3)
2x2+6x+x+3
2x2+7x+3 (2x2 means two x square)
if you want you can also multiply 2x+3 by x+3
like this:
(2x+1)(x+3)
x(2x+1)+3(2x+1)
2x2+x+6x+3
2x2+7x+3 (2x2 means two x square)
They will both give you the same answer.
Answer:
= 18 red marbles
Step-by-step explanation:
Let x be the number of red marbles that must be added
Therefore;
New number or red marbles = x+12
Total marbles will be x+32
Thus;
The probability of selecting a red marble = (x+12)/(x+32)
Therefore;
(x+12)/(x+32)=3/5
5(x+12)=3(x+32)
5x+60+3x+96
2x=36
x=18
