Question

Apply the distributive property to create an equivalent expression.
−9⋅(5j+k)=

Answer 1

`-45j-9k`.

Explanation:

The given expression is

`-9\cdot (5j+k)`

We need to find the equivalent expression of given expression.

According to the distributive property,

`a(b+c)=ab+ac`

Using distributive property the given expression can be rewritten as

`-9\cdot (5j)-9\cdot (k)`

`-45j-9k`

Therefore, the required expression is
`-45j-9k`.

Answer 2

Multiply the number outside the parenthesis by each term inside the parenthesis:

-9 * 5j = -45j

-9 *k = -9k

−9⋅(5j+k) = -45j - 9k
