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:
B)$319
Step-by-step explanation:
Interest each year is 275 × 4% = 275 × 4/100 = 11
total interest over 4 years is 4 x 11 = 44
total to repay after 4 years is 275 + 44 = 319
Use the distance formula: d² = (x₂ - x₁)² + (y₂ - y₁)²
d² = 50² + 80²
= 2500 + 6400
= 8900
d = √8900
= 94.3
Answer: 94.3 km
The answer for your problem is 3x-5y-15
