Question

A student used 3 steps to create an equivalent expression to the one shown below:

15x−(10+6)

a) 15x−(10+6)
b) 2x^2+8x+143
c) x^2+28x+143
d) x^2+14x+43

Answer 1

To create an equivalent expression to 15x-(10+6), follow these three steps: add 10 and 6 to get 16, combine the terms with x, and leave the expression as 15x-16.

Step-by-step explanation:

To create an equivalent expression to 15x-(10+6) in three steps, we need to simplify the expression inside the parentheses first:

1. Add 10 and 6 together to get 16: 15x-(10+6) becomes 15x-16.
2. Since there are no like terms to combine, we leave the expression as 15x-16.
3. So, the equivalent expression is 15x-16.

Answer 2
