Answer 2

To solve the equation (14y + 21)(1.8 - 0.3y) = 0, you can use the zero-product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be equal to zero. In this case, you have:

(14y + 21)(1.8 - 0.3y) = 0

Now, set each factor equal to zero and solve for y:

1. 14y + 21 = 0
2. 1.8 - 0.3y = 0

Let's solve each equation separately:

1. 14y + 21 = 0

Subtract 21 from both sides:

14y = -21

Now, divide by 14 to isolate y:

y = -21 / 14 y = -3/2

2. 1.8 - 0.3y = 0

Subtract 1.8 from both sides:

-0.3y = -1.8

Now, divide by -0.3 to isolate y:

y = -1.8 / -0.3 y = 6

So, there are two solutions for y:

y = -3/2 and y = 6.
