Answer:

(b) 32x^3 - y^3 + 42x^2y + 11xy^2 + 17

Step-by-step explanation:

To find the difference of the polynomials, write the equation expressing the difference, then simplify.

(19x^3 +44x^2y + 17) - (y^3 -11xy^2 +2x^2y -13x^3)

= (19 -(-13))x^3 -y^3 +(44 -2)x^2y +(-11)xy^2 +17

= 32x^3 -y^3 +42x^2y -11xy^2 +17

Multiplying a trinomial by a trinomial follows the same steps as multiplying a binomial by a trinomial. Determine the degree and

FinnZ [79.3K]

Answer: Degree of polynomial (highest degree) =4

Maximum possible terms =9

Number of terms in the product = 5

Step-by-step explanation:

A trinomial is a polynomial with 3 terms.

The given product of trinomial: $(x^2 + x + 2)(x^2 - 2x + 3)$

By using distributive property: a(b+c+d)= ab+ac+ad

$(x^2 + x + 2)(x^2 - 2x + 3)=(x^2 + x + 2) x^2+(x^2 + x + 2) (-2x)+(x^2 + x + 2)(3)\\\\=x^2(x^2)+x(x^2)+2(x^2)+x^2 (-2x)+x (-2x)+2 (-2x)+x^2 (3)+x (3)+2 (3)\\\\\\=x^4+x^3+2x^2-2x^3-2x^2-4x+3x^2+3x+6$

Maximum possible terms =9

Combine like terms

$x^4+x^3-2x^3+3x^2-4x+3x+6\\\\=x^4-x^3+3x^2-x+6$

Hence, $\left(x^2\:+\:x\:+\:2\right)\left(x^2\:-\:2x\:+\:3\right)=x^4-x^3+3x^2-x+6$

Degree of polynomial (highest degree) =4

Number of terms = 5

Helpppp nowww plsss!!!

mote1985 [20]

Answer: See explanation

Step-by-step explanation:

Multiples of 3: 3, 6, 9, 12, 15, 18

Multiples of 6: 6, 12, 18, 24, 30

The least common denominator is 6

1/3 can be rewritten as 2/6 and 4/6 can be rewritten as 4/6

Hope this helped!

What is the best estimate for this sum 1/8+1/6=The sum will be close to?

tamaranim1 [39]

The expression given is

$\frac{1}{8}+\frac{1}{6}$

The sum of the expression will be,

$\frac{1}{8}+\frac{1}{6}=\frac{6+8}{48}=\frac{14}{48}=\frac{7}{24}$

The sum will be

$\frac{7}{24}$
