Answer:
x^4 + 4x^3 + 8x^2 + 8x -5
Step-by-step explanation:
To make the product of two polynomials, simply apply the distributive property of multiplication, as follows:
(x^2 + 2x - 1)*(x^2 + 2x + 5)
x^2*x^2 + x^2*2x + x^2*5 + 2x*x^2 + 2x*2x + 2x*5 - 1*x^2 - 1*2x - 1*5
x^4 + 2x^3 + 5x^2 + 2x^3 + 4x^2 + 10x - x^2 - 2x - 5
The answer to your question is: x⁴ + 4x³ + 8x² + 8x - 5
(x² + 2x - 1)(x² + 2x + 5) = x⁴ + 2x³ + 5x² + 2x³ + 4x² + 10x - x² - 2x - 5
= x⁴ + 4x³ + 8x² + 8x - 5
Answer: A
Each gallon costs 3 dollars.
8(gallons) times $3(for each gallon) = 24(dollars).
200
20 X 1000= 20000 divided by 100
There are about 48 shells in Mrs. Reeds collection.
There are 16 ounces per 1 pound.
4 ounces per shell.
16 x 12 = 192 ounces
192 ounces divided by 4 = 48
B
Step-by-step explanation
115000 = 0.96p
115000 = p - 0.04p
I think It's B if the = sign in the beginning is a - sign
