Question

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

Answer 1

Answer:

$-45j-9k$.

Step-by-step 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
