Answer:

A. x² - x

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Terms/Coefficients/Degrees
  • Expand by FOIL (First Outside Inside Last)

<u>Geometry</u>

  • Area of a Rectangle: A = lw

Step-by-step explanation:

<u>Step 1: Define</u>

<em>l</em> = x

<em>w</em> = x - 1

<u>Step 2: Find </u><em><u>A</u></em>

  1. Substitute [AR]:                    A = x(x - 1)
  2. Distribute <em>x</em>:                          A = x² - x

andrew11 [14]

Answer:

Step-by-step explanation:

Given that the number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter μ = 20 (suggested in the article "Dynamic Ride Sharing: Theory and Practice"†).

a) P(X\leq 15) = 0.1565=0.157

b) P(X>26) =1-F(26)\\= 1-0.9221\\=0.0779=0.078

c) P(15\leq x\leq 26)\\=F(26)-F(14)\\=0.9221-0.1049\\=0.8172=0.817

d) 2 std dev = 2(20) =40

Hence 2 std deviation means

20-40, 20+40

i.e. (0,60)

P(0

Please please help me with geometry
telo118 [61]

These two angles are alternate interior, meaning that they are the same.

Therefore, 11x-10 = 2x+17

Solve to get x = 3; the two angles both equal to 23 degrees

and since EGF and DGE together form 90, DGE = 90-23 = 67

! + 3 − 5 = 0; by completing the square
mylen [45]

Answer:

x = 1.19258 and x = −4.19258

Step-by-step explanation:

The given equation is :

x^2+3x-5=0

Keep x terms on the left and move  the constant to the right side  by adding it on both sides.

x^2+3x=5

Take half of the x term and square it.

(3\times \dfrac{1}{2})^2=\dfrac{9}{4}

then add the result to both sides

x^2+3x+\dfrac{9}{4}=5+\dfrac{9}{4}\\\\(x+\dfrac{3}{2})^2=\dfrac{29}{4}\\\\(x+\dfrac{3}{2})=\sqrt{\dfrac{29}{4}}\\\\x=\dfrac{-3}{2}+\sqrt{\dfrac{29}{4}}\\\\x=\dfrac{-3}{2}-\sqrt{\dfrac{29}{4}}

So,

x = 1.19258 and x = −4.19258

Hence, this is the required solution.

denpristay [2]

Answer: 4x² + 3x + 52

Step-by-step explanation:

1. rearrange & simplify terms:

(4x² - 4 + 6) + (3x - 7² + 1) . . .

(4x² + 2) + (3x + 49 + 1) . . .  

 (4x²+2) + (3x + 50).

2. combine like terms in standard form:

<u>4x² + 3x + 52</u>
