Part 1: Writing Expressions
Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
Translate the algebraic expression you created in Question 1 to a verbal expression.

Expression: 5(2j + 3 + j)
= 5(3j + 3) = 15(j+1) = 15j + 15
Therefore, The equivalent expression is 15j + 15.
6(4j + 7 + 6j) is an expression non-equivalent to Sarah's expression.
This expression can be translated as:
"Sum of 4 times a number, 7 and 6 times the same number whole multiplied by 6".
