Berniece solved the following equation:

1 answer:

6 0

Step 4 is incorrect.

This is technically another example of the subtraction property of inequality. This is because we are subtracting 8 from both sides to get the 8 to cancel and the 24 to go down to 16. This is not addition and should not be justified as such.

Complete the factored form of the algebraic expression 18a + 3 = 3( _____+_____)

rodikova [14]

So to factorise an expression, you put it into a form where if you expanded the brackets, you'd get the given expression.. if that makes sense. Therefore, you need to multiply the 3 by something to get 18a, and so the first term is 6a. You don't need to multiply 3 by anything to get 3, so the second term is 1. The final result looks like:
3(6a + 1)
