Answer:
23. Congruent
24. Not congruent
Step-by-step explanation:
23. KJ and HL:
Since the side lengths are both 4 in, these segments are congruent.
24. EH and FG:
Since the side lengths are different numbers (0.45 cm and 0.5 cm), these segments are not congruent.

What is the factored form of this expression x^3+3x^2-6x-18
Answer:
(x + 3) (x^2 - 6)
Step-by-step explanation:
Factor the following:
x^3 + 3 x^2 - 6 x - 18
Factor terms by grouping. x^3 + 3 x^2 - 6 x - 18 = (x^3 + 3 x^2) + (-6 x - 18) = x^2 (x + 3) - 6 (x + 3):
x^2 (x + 3) - 6 (x + 3)
Factor x + 3 from x^2 (x + 3) - 6 (x + 3):
Answer: (x + 3) (x^2 - 6)

x=-5g(b)=5b-9
h(b)=(b-1)^2
(h*g)(-6) = ???
[tex](h \times \: g)(b) = (b - 1)^{2} (5b - 9) \\ = ( {b}^{2} - 2b + 1)(5b - 9) \\ = 5 {b}^{3} - 19 {b}^{2} + 23b - 9[/tex]
[tex](h \times \: g)( - 6) = 5( - 6) ^{3} - 19( { - 6}^{2}) + 23( - 6) - 9 \\ = 5( - 216) - 19(36) - 138 - 9 \\ = - 1080 - 684 - 138 - 9 \\ = - 1911[/tex]

The value of function (h·g)(b) for x=-6 is -867.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given functions are g(b)=5b-9 and h(b)=(b-1)².
Now, (h·g)(b)=h(b)×g(b)
= (b-1)²×5b-9
= (b²-2b+1)×(5b-9)
= b²(5b-9)-2b(5b-9)+1(5b-9)
= 5b³-9b²-10b²+18b+5b-9
= 5b³-10b²+23b-9
Now, (h·g)(-6)
= 5(-6)³-10(-6)²+23(-6)-9
= -1080+360-138-9
= -867
Therefore, the value of function (h·g)(b) for x=-6 is -867.

The pages in a book are numbered starting with one. The book has 250 pages. How many digits did the printer use in numbering the pages of the book? A. 640 B. 642 C. 320 D. 321
Answer:
B)642
Step-by-step explanation:
Between 1 and 9 , it will use 9 letters
Between 10 and 99, there are 90 different numbers and every number have 2 digits so it will use 180 letters
Between 100 and 250 , there are 151 different numbers and every number have 3 digits so it will use 453 letters
Totally it used 9+180+453=642
Sarah counted the number of tiles at each step and made a table. She explained that the
number of tiles in each figure was always 3 times the step number minus 2.
Create an equation that fits Sarah's way of seeing the relationship.
PLS HELP DUE IN 10 min!!
Answer:
n(number of tiles) x 3 - 2
Step-by-step explanation:
times mean multiplication and minus mean subtraction, I hope this helps.
An equation is formed of two equal expressions. An equation that fits Sarah's way of seeing the relationship is y = 3x - 2.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
As stated by Sarah that "the number of tiles in each figure was always 3 times the step number minus 2", this can be written in the form of an equation as shown below.
Number of tiles = [3 × (Number of steps)] - 2
Assume that the number of tiles is represented by y, while the number of steps can be written as x. Therefore, we can write the equation as,
y = 3x - 2
Now, let's check the equation,
When the number of steps is 3, the number of tiles is 7.
y = 3(3) - 2
y = 9 - 2
y = 7
Since the number of tiles is the same, therefore, the equation is correct.
Hence, an equation that fits Sarah's way of seeing the relationship is y = 3x - 2.

Perimeter:
PLEASE HELP
Answer:
14x + 4
Step-by-step explanation:
The perimeter of a rectangle is the sum of all its sides. The rectangle have two sides with length 5x + 2, so:
(5x + 2)×2 = 10x + 4
And it also have two sides with length 2x, so:
(2x)×2 = 4x
And now just add it:
10x + 4 + 4x = 14x + 4
Answer: Perimeter = 14x + 4
Concept:
Here, we need to know how to find the perimeter of a rectangle.
Perimeter (rectangle) = 2 (l + w)
l = length
w = width
If you are still confused, you may refer to the attachment below for a graphical explanation.
Solve:
Given information
l = 5x + 2
w = 2x
Given expression
Perimeter = 2 (l + w)
Substitute values into the expression
Perimeter = 2 (5x + 2 + 2x)
Combine like terms
Perimeter = 2 (7x + 2)
Expand parentheses and apply the distributive property
Perimeter = 2 · 7x + 2 · 2
Perimeter = 14x + 4

Step-by-step explanation:
1.) two tails :
total no. of outcomes possible is TT,TH,HT,HH
no. of outcomes with TT is 1
p( tails on both) = 1/4
2.) tails at least one:
no. of outcomes with one tails atleast is 3 (TT,th,ht,)
p( atelast one tails) = 3/4
3.) tails on one
no. of outcomes with one tails at most is 2 (th,ht)
p( atmost one tails) is 2/4= 1/2
4. no tails
no. of outcomes with no tails is 1(HH)
p( no tails) = 1/4
hope it's understandable.
Answer:
1.) two tails :
total no. of outcomes possible is TT,TH,HT,HH
no. of outcomes with TT is 1
p(tails on both) = 1/4
2.) tails at least one:

Answer:
Step-by-step explanation:
The set of all real numbers except for 100 in set builder notation (assuming the variable is x) is:
The very first x represents the variable.
The second with the R represents the number. Here, we want all real numbers.
And the third is the constraint. We want all real numbers except for 100.
Answer:
{ x | x ∈ R, x ≠ 100 }
Step-by-step explanation:
Real numbers (R) include all rational and irrational numbers.
Hence, If we need to write it in set-builder notation, we will write as:
{ x | x ∈ R, x ≠ 100 }
In words : "x such that x belongs to R, x is not equal to 100"
This shows that x is any real number except for 100.
