Answer:
5.3x^3+11.1x+0.8
Step-by-step explanation:
Add ones with similar variables
5.3x^3+11.1x+0.8
So 1 5/8 + 2/3 = 13/8 + 2/3
convert the fractions to a common denominator
39/24 + 16/24
55/24
=2 7/24 quarts of paint
Answer:
8.5
Step-by-step explanation:
First we need to get BC using the pythagoras theorem
BC² = AC² + AB²
BC² = 8² + 15²
BC² = 64+225
BC² = 289
BC = √289
BC = 17
DB = 1/2BC
DB = 1/2 * 17
DB = 8.5
Hence the length of DB is 8.5

Step-by-step explanation:
Given: The low temperature on Monday was 16°F. The low temperature on Tuesday was 18°F cooler. The low temperature on Wednesday was –4 times Tuesday’s temperature.
To find: expression that can be used to describe the low temperature on Wednesday
Solution:
Temperature on Monday = 16°F
So,
Temperature on Tuesday = 
Temperature on Wednesday = 
So, expression
can be used to describe the low temperature on Wednesday.
Also,
\,\,\left \{\because (a-b)=\left [ a+(-b) \right ] \right \}](https://tex.z-dn.net/?f=%2816-18%29%28-4%29%3D%5B16%20%2B%20%28-18%29%5D%28-4%29%5C%2C%5C%2C%5Cleft%20%5C%7B%5Cbecause%20%20%28a-b%29%3D%5Cleft%20%5B%20a%2B%28-b%29%20%5Cright%20%5D%20%5Cright%20%5C%7D)
So, expression
also represent temperature on Wednesday.
