3 + -25 = -22
3 x -25 = -75
Answer:
g(n) = 2n^2 - 4n; Find g(-9)
The answer is 170, because you have to plug in -9 for all the N values. When you do that, just follow PEMDAS.
P-Parentheses
E-Exponents
M-Multiplication
D-Division
A-Addition
S-Subtraction
Step-by-step explanation:
g(-9) = 2(-9)^2 - 4(-9)
g(-9) = 18^2 -4(-9)
g(-9) = 134+36
g(-9) = 170
I really hope this helps!

Answer:
She got $30.15 more for selling the juice than she paid to buy it
Step-by-step explanation:
<u><em>Britney bought 3 gallons of juice for $2.75 per gallon. She sold the juice 1-cup servings for $0.80 each. Each serving is 1/16 gallon. How much more did She get for selling the juice than she paid to buy it?</em></u>
To solve the problem, we will follow the steps below;
1 gallon = $2.75
3 gallons = 3× $2.75 =$ 8.25
We will find the number of servings in in 3 gallons
1- cup serving = 1/16 gallon
number of serving = 3 gallons ÷ 1/16 gallon
= 3×16
= 48
But each cup serving = $ 0.80
48 servings = 48×$0.80 = $38.4
How much more She got for selling the juice than she paid to buy it =
$38.4 - $ 8.25 =$30.15
Answer:
47.5 is correct
Step-by-step explanation:
use the Pythagorus theorem
31^2+36^2= BA^2
2257=BA^2
square root both sides
√2257= 47.50789408
round to the nearest tenth
47.5
Answer:
Step-by-step explanation:
x⁸ - 6561 = x⁸- 3⁸ = (x⁴)² - (3⁴)²
= (x⁴ + 3⁴) (x⁴ - 3⁴) {a² - b² = (a+b)(a-b); here a =x⁴ and b= 3⁴ }
= (x⁴ + 3⁴) ( [x²]² - [3²]²) {here a =x² and b = 3²}
= (x⁴ + 3⁴) (x² + 3²) (x²- 3²)
= (x⁴ + 81) (x² + 9) (x + 3) (x-3)
