Identify in the following expressions terms which are not constant and give thier numerical coefficients: a) a+b+5

b) 2x ²y - 3xy² + 7

c) 11 - p²

d) 13 - p + 5q²

step-by-step explanation:

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

x=25tan30=14.43 or the answer is b

all of them are elements inside set of real numbers since none of them appears to have complex number form.

hope this .
