If you are looking to simplify these equations, here is how you would go about doing so.
7w(-8+3w)
Use a property called the Distributive Property, which means multiplying the number outside of the bracket by each number inside of the brackets.
Here is how this would look:
7w(-8+3w)
-56w+21w²
Now,
6q(-4+8q)
-24q+48q²
Hope this helps.
Answer:
14.91288 miles
Step-by-step explanation:
We can use a proportion to solve this problem. Put the distance over the cost. We want our answer in miles so we need to convert 8 kilometers to miles. 1 km = .621371 miles
8 km * .621371 miles/ 1 km = 4.971 miles
4 .971 miles x miles
--------------------- = ------------------
10 dollars 30 dollars
Using cross products
4.971 * 30 = 10x
149.1288= 10 x
Divide by 10 on each side
149.1288/10= 10/10 x
14.91288 =x
