What is the sum of the polynomials? (7x -4x²) + (2x² - 4x²)

(7x³-4x²)+(2x³-4x²) = 7x³-4x²+2x³-4x² = 9x³ - 8x²

Step-by-step explanation:

7x - 6x² or    -6x² + 7x

Step-by-step explanation:

(7x-4x²) + (2x²-4x²)

7x - 4x² + 2x² - 4x² = 7x - 8x² + 2x² = 7x - 6x²

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
