Step-by-step explanation:
So, you need to add 
on both sides of the quadratic equation.
Answer:
x=25
Step-by-step explanation:
Since both triangles are similar, you can set them up as a proportional problem
x/20=32/(8+20+12) Solve for x, you can so cross multiply method.
32x=800
x=25
Answer:
The measure of the outside angle is the sum of the two inside angles:
68+52=120
Or you could do it the long way and find the third angle inside the triangle then do 180 minus that but this is easier.
Step-by-step explanation:
I think you want to convert it all to feet.
1 mile = 5,280 feet
2 miles = 5,280 × 2
5,280 × 2 = 10,560 feet
10,560 + 500 = 11,060 feet
2 miles and 500 feet is equal to 11,060 feet
Your total profit is $13,000. First you bought the 200 items for $20 each. That costs $4,000. Then you sold $50 of the items at $100 each. That’s $5,000. So already you’re in the green. You’ve already made $1,000 profit. Then you sold the rest of the items at a 20% discount. 150 items multiplied by $80 is $12,000. $12,000 plus the $1,000 equals $13,000 total.
