May you please tell me what is 9(2a+1)

18a + 9

Step-by-step explanation: So let's simplify this problem using the distributive property.

The first thing we want to do is distribute or multiply this 9 times each of the terms inside the set of parentheses.

So we get 9 times 2a + 9 times 1.

So we have 9 (2a) + 9 (1) and this simplifies to 18a + 9.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
