Question

7.EE.1.1 Mario has read two less than four times the number of books Tonya has read. What factored expression represents the number of books, x, Mario has read? A. 4x - 2 B. 2(x - 1) C. 4(x - 2) D. 2(2x - 1)(It isnt A)

Answer 1

Tonya books = x

Mario books = 4x-2

we can factorize the expression by a common factor, in this case, is 2, because 2 is divisible between 4 and 2.

`4x-2=2(2x-1)`

the correct answer is D.
