Answer:

C. 2x^2 -2x+16 cm

Step-by-step explanation:

Length = x+5\\Width = x^2-2x+3\\\\Perimeter = 2(L+B)\\P = 2((x+5)+(x^2-2x+3))\\\\\mathrm{Remove\:parentheses}:\quad \left(a\right)=a\\P =2\left(x+5+x^2-2x+3\right)\\\\\mathrm{Simplify}\:x+5+x^2-2x+3:\quad x^2-x+8\\P = 2\left(x^2-x+8\right)\\\\P  = 2x^2 -2x +16\:cm

Graph x/8 is greater than 2÷(3+4+1)×2
Mice21 [21]
X/8 > 2÷(3+4+1)×2 can be simplified as:

x/8 > 2÷(3+4+1)×2
= x/8 > 1÷(3+4+1)
= x/8 > 1÷(8)
= x/8 > 1/8
= x > 1
As shown in the attached picture, the red shaded part is the graph of x>1

What is the simplified form of the quantity of x plus 6, all over the quantity of x plus 4 + the quantity of x minus 3, all over
11Alexandr11 [23.1K]

Answer:

<u>(x² + 4x + 6)/ 3x + 12</u>

<u>This is the most simplified form</u>

Step-by-step explanation:

Let's simplify the expression:

(x + 6)/(x + 4) + (x - 3)/3

Least Common Denominator : 3 * (x + 4)

[3 * (x + 6) + (x - 3) (x + 4)]/ 3 * (x + 4)

Solving parentheses:

[3x + 18 + x² - 3x + 4x - 12]/ 3 * (x + 4)

Like terms:

<u>(x² + 4x + 6)/ 3x + 12</u>

<u>This is the most simplified form</u>
