In the expression x2 + 4x2 + 16x2, x2, 4x2, and 16x2 are examples of a) coefficients b) like terms c) operations d) variables

x^2, 4x^2, and 16x^2 are examples of like terms

Step-by-step explanation:

In the expression are examples of ____

Given expression is

All the terms have same variable with same exponent.

Same exponent with same variables are called like terms.

In the given expression, all terms have same variable x^2

So x^2, 4x^2, and 16x^2 are examples of like terms

right

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
