A rectangle. one side is 2x + 7 and the other is x+3

saveliy_v [14]

$\large{\green}\fcolorbox{purple}{pink}{\bf{\underline{\red{\color{red}Answer}}}}$

6x + 20

Step-by-step explanation:

To find :-

Perimeter of rectangle

Given :-

Length = 2x + 7

Breadth/width = x + 3

Solution :-

We know that

$\mathfrak {perimeter \: of \: rectangle =2(length + breadth) }$

Now we will substitute the values of length and breadth

$\sf \longmapsto perimeter = 2 \{(2x + 7) + (x + 3) \} \\ \\ \\ \sf \longmapsto perimeter = 2 \{3x + 10 \} \\ \\ \\ \sf \longmapsto perimeter = 6x + 20$

Compare the two functions:

Ilya [14]

Answer:

One example is the equation:

2x + 6 = 4x/2 + 12/2

To solve this, we need to transpose like terms to the same side.

2x - 4x/2 = 12/2 - 6

2x - 2x = 6 - 6

0 = 0

Since both sides are zero, it means that the equation has infinite number of solutions.

What is the degree of the polynomial? 5x² + 8x³ + 4- 6x² - 3x5

geniusboy [140]

Answer:

The degree of polynomial is 5.

Step-by-step explanation:

I suppose the polynomial is $\displaystyle{5x^2+8x^3+4-6x^2-3x^5}$ . To find the which degree this polynomial is, we consider the highest exponent of the term which is $\displaystyle{3x^5}$ , the 5 is our highest degree of the term and thus, 5 is our highest degree of polynomial.
