which expression is equivalent to 5y (8y-3)?

Answer 1

To simplify the expression $5y(8y-3)$, you can use the distributive property, which states that $a(b+c)=ab+ac$.

Applying the distributive property to $5y(8y-3)$:

$$5y(8y)-5y(3)$$

Calculating each term:

1. $5y\cdot 8y=40y^2$
2. $5y\cdot 3=15y$

Putting it all together, we get:

$$5y(8y-3)=40y^2-15y$$

Therefore, the expression equivalent to $5y(8y-3)$ is $40y^2-15y$.
