Answer:
4n - 2
Step-by-step explanation:
Greater = 2n
Smaller = 2n - 2
Sum = 2n + (2n - 2)
Sum = 2n + 2n - 2
Sum = 4n - 2
Answer: 8x³ - 7x² - 6x + 5
Step-by-step explanation:
8x³ - 7x² - 6x + 5 is a cubic expression.
The variable is x
The variable x has highest power as 3.
8x³ - 7x² - 6x + 5 is a polynomial.
-7x + 4 is a linear expression because highest power of the variable x is 1.
7x² - 5x + 6 is a quadratic expression because the highest power of the variable x is 2.
9x^4 + 8x^3 - 6x^2 - 2x + 11 is a polynomial with the highest power of the variable being 4.
Answer:
Step-by-step explanation:
Given:
Grocery store: 8 ounces of blueberries = $2.80
Farmer's market : 14 ounces of blueberries = $4.20
1 pound = 16 ounces.
Unit rate: per ounce
Grocery store: $2.80 ÷ 8 oz = $0.35 per ounce
Farmer's market: $4.20 ÷ 14 oz = $0.30 per ounce
Unit rate per pound
Grocery store: $0.35 per ounce * 16 ounces = $5.60 per pound
Farmer's market: $0.30 per ounce * 16 ounces = $4.80 per pound
