Hello!

x² + 5x + 6
Find two numbers that add up to 5 and multiply to 6. We get:
2, 3
Therefore:
(x + 2)(x + 3)
68°+52°=120 and a triangle is 180° so 180-120=60 so x=60
shortest to greatest 52, 60, 68
Answer:
Shoes with discount = $17
Necklace = Price * 0.85
Step-by-step explanation:
-If the tennis shoes store sells other things than shoes-
Shoes = $20.00
Discount = 15%
*Price expressed as a percentage*
Price without discount = 100%
Price after discount = 100% - 15%
Price after discount = 85%
*Normal price*
Price without discount = 20
Price after discount = 20 * 0.85
Price after discount = 17
