What is the correct factorization of:
x? - 11x + 18
Answers
9514 1404 393
Answer:
x² -11x +18 = (x -9)(x -2)
Step-by-step explanation:
The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.
18 = (-1)(-18) = (-2)(-9) = (-3)(-6)
The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...
x² -11x +18 = (x -9)(x -2)

The difference of the squares of two positive consecutive even integers is 84. Find the integers.
Answers
Answer:
The two integers are 20 and 22.
Step-by-step explanation:
Let x be the first integer.
[tex](x+2)^{2}-x^{2} = 84\\x^{2} +4x+4-x^{2} = 84\\4x = 80\\x = 20[/tex]
Applying the difference of squares, and solving the equation, it is found that the numbers are 20 and 22.
----------------------
The two consecutive even integers are: n and n + 2.The difference of the squares is given by:[tex]D_s = (n+2)^2 - n^2[/tex]
Expanding the difference:
[tex]D_s = n^2 + 4n + 4 - n^2[/tex]
[tex]D_s = 4n + 4[/tex]
----------------------
The difference is 84, thus:
[tex]D_s = 84[/tex]
Now, we solve for n.
[tex]4n + 4 = 84[/tex]
[tex]4n = 80[/tex]
[tex]n = \frac{80}{4}[/tex]
[tex]n = 20[/tex]
----------------------
Thus, the numbers are: [tex]n = 20[/tex] and [tex]n + 2 = 20 + 2 = 22[/tex]

find the number of words with or without meaning , which can be made by using all the letters of word ganga
Answers
Answer:
There are total 5 letters , of which A occur two times and G occur 2 times
Therefore , The number of permutations starting with A is 4! i.e 24
Thus , 25th word will be start from G i.e GGAAN
By rearranging according to the dictionary , we get
The 26th word will be GGANA
Hence , the 26th word is GGANA
Answer:
30
Step-by-step explanation
total number of letters in the word, n = 5
out of which G and A repeats 2 times each
p1 = p2 = 2
according to the equation of number of permutations,
= [tex]\frac{n!}{p_{1}! p_{2}! }[/tex]
total number of words = 5!/ (2! x 2!)

Answers
Given,
The four numbers are consecutive
The numbers are
x
x + 1
x + 2
x + 3
Sum = -34
x + (x + 1) + (x + 2) + (x + 3) = -34
x + x + 1 + x + 2 + x + 3 = -34
(x + x + x) + (1 + 2 + 3) = -34
3x + 6 = -34
3x = -34 - 6
3x = -40
x = -40/3

You are a landscaper, and you are designing a fence to enclose part of a yard. The section to be enclosed is rectangular and has a width of 21 feet and a length of 38 feet. What length of fence, in feet, will you need to enclose this part of the yard? 59 60 118 120 798
Answers
Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area

This illustrated on a graph where y axis is the area and x axis is the width:

Answers
Answer:
495 ways
Step-by-step explanation:
Given that:
Total number of applicants (n) = 12
Required number (r) = 4
Using the combination formula :
nCr = n! / (n-r)!r!
12C4 = 12! / (12 - 4)!4!
12C4 = 12! / 8!4!
12C4 = (12*11*10*9) / 4*3*2*1
12C4 = 11880 / 24
= 495 ways
