On a math test a student, Sarah, has to identify all the coefficients and constants of the expression 9 b + 4 + y. Sarah says that 9 is a coefficient and 4 is a constant. Identify all the coefficients and constants of the expression. What error might Sarah have made?

Step-by-step explanation:

4 + n + 7m

constants are just the numbers with no variables (letters)

so the constant is 4

coefficients are numbers multiplied by variables (letters)

so the coefficients are : 7 and 1

the error sarah made is forgetting the coefficient of nbecause even if it is not written, n is the same as 1nso basically, there is a coefficient for EVERY variable, even if its not written.

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
