Answer: Last option is correct.

Step-by-step explanation:

Since we have given that

7x^3-4x^2+2x^3-4x^2

We need to find the sum of the polynomials:

So, we first collect the like terms:

7x^3-4x^2+2x^3-4x^2\\\\=7x^3+2x^3-4x^2-4x^2\\\\=9x^3-8x^2

Hence, the sum of polynomials is 9x^3-8x^2

Therefore, Last option is correct.

9x^3 - 8x^2 is the answer. to solve this you must distribute the sign across each parenthetical and then add the like terms (all cubed x variables added to cubed variables and all squared x variables added to squared variable)

Elina [12.6K]

Answer:

Step-by-step explanation:

y = ax² + bx + c

~~~~~~~

(4, - 2), (8, 6), (2, 0)

a(4²) + b(4) + c = - 2

a(8²) + b(8) + c = 6

a(2²) + b(2) + c = 0

16a + 4b + c = - 2 .............. <em>(1)</em>

64a + 8b + c = 6 ............... <em>(2)</em>

4a + 2b + c = 0 ................. <em>(3)</em>

a = 0.5 ; b = - 4 ; c = 6

<em>y = 0.5x² - 4x + 6</em>

Part A: (0, 6), (6, 0)

Part B: (0,6)

Part C: (6, 0)

Part D: [ 4, ∞ )

2.199 rounded to the nearest whole number
steposvetlana [31]
Rounding 2.199. The tenths digit is 1, which is 4 or less, so you will round down. Re-write 2.199 without the decimal places: 2 . So 2.199 rounds to 2.
