consider the followin polynomials equations a=3x2(x-1) b= -3x3+4x2-2x+1 . perform each operation and determine if the result is
Sedaia [141]

Answer:

All three operations lead to polynomials.

See explanations below.

Step-by-step explanation:

Polynomial a = 3x^2(x-1)=3x^3-3x^2

Polynomial b = -3x^3+4x^2-2x+1

Therefore:

a + b = 3x^3-3x^2+(-3x^3+4x^2-2x+1)=\\=3x^3-3x^2-3x^3+4x^2-2x+1=\\=x^2-2x+1

where we have combined all like terms. This is clearly another polynomial (of grade 2)

a - b (here we need to flip all signs inside the parenthesis when we remove this grouping symbol):3x^3-3x^2-(-3x^3+4x^2-2x+1)=\\3x^3-3x^2+3x^3-4x^2+2x-1=\\6x^3-7x^2+2x-1

which is clearly another polynomial (but of grade 3)

a * b : (here we use distributive property to multiply each term of the first polynomial by each term of the second one, and then combine like terms)

(3x^3-3x^2)*(-3x^3+4x^2-2x+1)=\\-9x^6+12x^5-6x^4+3x^3+9x^5-12x^4+6x^3-3x^2=\\-9x^6+21x^5-18x^4+9x^3-3x^2 which is indeed another polynomial (this time of grade 6)

A rectangle has a height of 4x and a width of 3x+1
anastassius [24]

Answer:

12^2 + 4x

Step-by-step explanation:

We need to solve the area of these two rectangles separately.

Equation: 4x(3x+1) --> 12x + 4

Area: 12x^2 + 4x

Hope this helps.

The ratio of w to x is 4 to 6. the ratio of y to x is 1 to 3. what is the ratio of w to y?
AlekseyPX

Answer:

2:1

Step-by-step explanation:

w:x = 4:6

y:x = 1:3

if w = 4 and x = 6, y = 1/3x = 2

If w = 4 and y = 2, then the ratio is;

w:y = 2:1
