Which polynomial represents the sum below (x^8 + 2x^4 + 1) + (2x^4 + x^2 + 1)
Serggg [28]

To add the polynomials \tt {x}^{8}  +  {2x}^{4}  + 1 and \tt {2x}^{4}  +  {x}^{2}  + 1 let us first combine the like and unlike terms and add them :

=\tt  {x}^{8}  +  {2x}^{4}  + 1 + \tt {2x}^{4}  +  {x}^{2}  + 1

= \tt {x}^{2}  +  {x}^{2}   +  {x}^{2} +  {x}^{2}  +  {2x}^{2}  +  {2x}^{2}  +  {2x}^{2}  +  {2x}^{2} +  {x}^{2}  + 1 + 1

=\tt  {13x}^{2}  + 2

<h3>○=> Therefore :</h3>

\color{hotpink} = \tt  {x}^{8}  +  {2x}^{4}  + 1 + \tt {2x}^{4}  +  {x}^{2}  + 1 \color{plum}=  {13x}^{2}  + 2

What is the remainder when the polynomial f(x)=3x^3-4x^2+2x+8 is divided by (x-5)
yaroslaw [1]

The remainder when the polynomial f(x) = 3x³ - 4x² + 2x + 8 is divided by (x - 5) is constant an equal f(5).

Substitute x = 5 to the polynomial:

f(5)=3(5^3)-4(5^2)+2(5)+8=3(125)-4(25)+10+8\\\\=375-100+18=275+18=293

Answer: (3x³ - 4x² + 2x + 8) : (x - 5) = q(x) + 293.

115% of what number is 120?
antiseptic1488 [7]
115% is the same as 1.15
some number = x

115% of some number is 120
1.15 of x is 120
1.15 * x = 120
\frac{1.15*x}{1.15} = \frac{120}{1.15}
x = 104.3478
x ≈ 104.3

Hope this helps! :)

Name:
qaws [65]

Answer:

Width of the rectangle = 5 inches

Length of the rectangle = 20 inches

Step-by-step explanation:

Let us assume the width of the rectangle = m  in

So, the length of the rectangle = 4 (Width) = (4 m) in

Perimeter of the rectangle = 50 inches

Now, Perimeter of the Rectangle = 2 (LENGTH + WIDTH)

⇒ 2( m + 4m)  = 50

or, 2(5m) = 50

⇒ 10m = 50  or, m = 50/10 = 5

⇒ m = 5

So, the width of the rectangle = 5 inches

and the length of the rectangle = 4 m = 4 x 5 = 20 inches
