At a library book sale, hardcover books sell for $4 and paperbacks sell for $2. the expresstion 4b+2b represents the total cost for b hardcover books and b paperbacks. write a simpler expression that is equivalent to 4b+2b

6b is a simpler expression that is equivalent to 4b+2b.

Step-by-step explanation:

 Given : At a library book sale, hardcover books sell for $4 and paperbacks sell for $2.

  The expression 4b+2b represents the total cost for b hardcover books and b paperbacks.

We have to write a simpler expression that is equivalent to 4b+2b.

Equivalent expression are expression which are different in seeing but when we solve both we get the values same  as the original expression.

Given expression is 4b+2b,

We can take 2b common from terms to get an equivalent expression as,

4b+2b = 2b(2+1) = 2b(3) = 6b.

Thus, 6b is a simpler expression that is equivalent to 4b+2b.

Answer : 6b

Step-by-step explanation: b (4+2)

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
