Step-by-step explanation: double the product of two numbers is always 2(x + x) and when one is unknown you use x as stated and 3 plus x is 3 +x so the answer is 2(3 + x)
All of these can be captured by the algebraic statement 3x + 2x = 5x, for any number of x. The product of 3 and x; x is multiplied by 3, or 3 is multiplied by x. 2 terms are called like terms if they involve exactly the same pronumerals and each term. The terms 3x and 3x2 are not like terms because the indices are different.
