3. Study the numerical expression 7 x (9-3). Which one of the following expressions is equivalent to this numerical expression? A. Multiply 7 by the difference between 9 and 3.
B. Multiply 7 by 9, then subtract 3.
C. Subtract 3 from the product of 7 and 9.
D. Three less than the product of 7 and 9.

Step-by-step explanation:

First step is to do whatever is in the parentheses: 9-3.

Then you will multiply 7 by that number; which will give you the answer.

B is correct because it does it that way.

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros
