Question

If C = 2y 1 and D = y - y², find an expression that equals 3C + D in standard
form.

Answer 1

To find an expression that equals 3C + D in standard form, substitute the given definitions of C and D into the expression and simplify.

Step-by-step explanation:

To find an expression that equals 3C + D in standard form, we substitute the given definitions of C and D into the expression.

Given that C = 2y + 1 and D = y - y², we can substitute these values into 3C + D as follows:

3C + D = 3(2y + 1) + (y - y²)

Simplifying this expression, we get 6y + 3 + y - y². Rearranging the terms in standard form, we obtain -y² + 7y + 3.
