4. on a math test, sarah has to identify all the coefficients and constants
of the expression 4+n + 7m. sarah identifies the only coefficient as 7 and
the only constant as 4.

a. identify all the coefficients of the expression.
total
b. identify all the constants of the expression.
c. what error did sarah likely make?
5 +4.10)

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.

$450 i think. hope this ☺
