Question

Нужно решить при меняя распределительное свойство умножение 9(3-y)+15 =?

Answer 1

9(3-у)+15=27-9у+15=42-9у

Answer 2

Solving the Expression Using the Distributive Property

To solve the expression 9(3-y) + 15, we can use the distributive property of multiplication over addition. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac.

Applying the Distributive Property

We can apply the distributive property to the given expression as follows:

9(3-y) + 15 = 9*3 - 9*y + 15

Simplifying the Expression

Now, let's simplify the expression:

9*3 - 9*y + 15 = 27 - 9y + 15

Combining Like Terms

Finally, we can combine like terms to get the simplified expression:

27 - 9y + 15 = 42 - 9y

So, the simplified form of the expression 9(3-y) + 15 is 42 - 9y.
