Answer:

  a) (x +2)(x +3)

  b) x = -2 or -3

Step-by-step explanation:

a) The constants in the binomial factors will be divisors of 6 that have a sum of 5. You know that ...

  6 = 1×6 = 2×3

The sums of these factor pairs are 7 and 5. You want the pair 2, 3. The factors are ...

  x² +5x +6 = (x +2)(x +3)

__

b) The solutions to the equation are the values of x that make the factors zero:

  (x +2) = 0   ⇒   x = -2

  (x +3) = 0   ⇒   x = -3

A construction company uses the function f(p) where p is the number of people working on a project to model the amount of money
Jlenok [28]

Answer:

Domain of f(p) =  [0,∞), where it belongs to whole numbers only

Step-by-step explanation:

The domain is the set of all possible values of independent variable for which function is defined

As in the given function f(p), we have the independent variable p. As p is the number of people working on the project, so it means either the number of people could be 0 or it could be anything greater than 0,  like it could be equal to thousand or ten thousand, but it can not be fraction in any case.

So, the domain is set of whole numbers starting from 0.

Domain of f(p) = [0,∞)

Can any one help me with this problem
katrin [286]

Answer:

37.74 ft

Step-by-step explanation:

An angle and its opposite side are known

Sin (of the angle)= opposite/ hypotenuse

The hypotenuse is equal to the length of the ladder, therefore solve the hypotenuse

Sin (32)= 20/ hypotenuse

hypotenuse= 20/ Sin (32)

Sin (32)=0.5299

hypotenuse= 20/ 0.5299

37.74 ft

Hopefully this helps :)

Write the equation below in slope-intercept form. <br><br> x - y = 2
Arte-miy333 [17]

slope intercept form

y=mx+b

x-y =2

we need to subtract x from each side

x-y-x = -x +2

-y = -x+2

multiply each side by -1

-1*-y = -1(-x+2)

y = x -2

the slope intercept form is

y = x-2

Which of the following is true?
mart [117]
<span>-6.175 is an irrational number:  FALSE.  -6175/1000 is a rational number.

4.8⁢33¯ is a rational number but not an integer.  TRUE  This is a repeating decimal, equal to 4 5/6, or 29/6, both of which are rational fractions.

0 is neither a rational number nor an irrational number.  I'd say FALSE.  0/0 appears to be rational, but div. by zero is undefined.  

Square root 2 is an integer.  FALSE.  Definitely not.
