Answer:

A -60i - 14j

Step-by-step explanation:

u = -9i + 8j

v = 7i + 5j

2u = 2(-9i + 8j) = -18i + 16j

6v = 6(7i + 5j) = 42i + 30j

2u - 6v

(-18i + 16j) - (42i + 30j)

(-18i - 42i) + (16j-30j)

-60i - 14j

Identify the property used in Step 3.
svp [43]

The associative property has been used in step 3

Step-by-step explanation:

There are multiple properties that are used to solve the equations

One of them is associative property.

Associative property states that the order of three terms which are being added doesn't matter the result will be same.

a + (b+c) = (a+b)+c

In step 2:

2 + 2x + 10 + (-10 + 11x)

As we can see that the last three terms are being added

The solver has used the associative property to solve the expression.

2 + 2x + [10 + (-10)] + 11x

The brackets have been changed from 10+(-10+11x)\ to\ [10 + (-10)} +11x using associative property

The associative property has been used in step 3
