Answer:
The answer is c
Step-by-step explanation: Since both terms are perfect squares, factor using the difference of squares formula to get the answer i hope this helps
Hey there!
The answer is C.
To factor an expression, you take the root (same as exponent variable has) of the terms and put them into parantheses. We can also check the choices to see if they're correct by solving them.
A is incorrect, because if you solve it, you would have [tex]x^2-121[/tex]
B is incorrect, because if you solve it, you would have [tex]121x-x^2[/tex]
C is correct, because if you solve it, you would have [tex]121-x^2[/tex]
D is incorrect, because it CAN be factored.

Joanna is selling tickets for the school play $he ha$ already $old $35
worth of tickets. $he ha$ seven ticket$ left to sell for $5 per ticket. write
function to describe the total amount of money collected if she sells every single ticket
Answer:
okay, so given we have that she has already sold $35 worth of tickets. We know that she has seven tickets left to sell, and each is worth $5. So, we would do 7×$5=$35
Next, we would add $35(from the previous money she has made) and $35 (the money she just made from the 7 tickets) and that would equal $70
equation: y=35+7(5)

Use the Remainder Theorem to evaluate f(10) for:
f(x) = 2x^3 – 14x^2 - 56x - 40
Step-by-step explanation:
Since we are told that 10 is a zero,
(x−10) must be a factor:
F(x)=2x3−14x2−56x−40
F(x)=(x−10) (2x2+6x+4)
F(x)=2(x−10)(x2+3x+2)
F(x)=2(x−10)(x+2)(x+1)
So the other two zeros are
x = -2 and x= −1
If the Pixie Sticks cost 4.50 per pound and Nicholas spends 8.10, How many pounds did he purchase?
Answer:
Step-by-step explanation:
Nicholas has purchased 1.8 pounds of pixie sticks.
Jane has purchased 3.0 pounds of Jolly ranchers.
Step-by-step explanation:
Cost of 1 pounds of pixie sticks = $4.50
Let the number of pixie sticks = x
Total money spend on x pounds of pixie sticks = $8.10
Nicholas has purchased 1.8 pounds of pixie sticks.
Cost of 1 pounds of Jolly ranchers = $3.25
Let the number of Jolly ranchers = y
Total money spend on y pounds of Jolly ranchers = $9.75
Jane has purchased 3.0 pounds of Jolly ranchers.
Express the function h(x)= 1/x-6 in the form of f o g. If g(x)=(x-6), find the function f(x).
Answer:
f(x) = 1/x
Step-by-step explanation:
h(x) = f(g(x)) = f(x-6) = 1/x-6
1/x-6 could only be accomplished if f(x) = 1/x
Assuming f(x) = 1/x and g(x) = x-6, f(g(x)) = f(x-6) = 1/x-6
Since f(g(x)) = 1/x-6 = h(x), we've proven that f(x) = 1/x.
The given functions are illustrations of a composite function, where the function f(x) is:
[tex]f(x) = \frac{1}{x}[/tex]
Given that:
[tex]h(x) = \frac{1}{x - 6}[/tex]
[tex]g(x) = x - 6[/tex]
f o g can be written as f(g(x))
So, we have:
[tex]h(x) = f(g(x))[/tex]
Rewrite as:
[tex]f(g(x)) = \frac{1 }{x - 6}[/tex]
Substitute g(x) for x - 6
[tex]f(g(x)) = \frac{1 }{g(x)}[/tex]
Replace g(x) with x
[tex]f(x) = \frac{1}{x}[/tex]
Hence, the function f(x) is: [tex]f(x) = \frac{1}{x}[/tex]

4x-3y = 12 and 3x+2y =6
Answer:
x = 42/17
y = -12/17
Step-by-step explanation:
4x - 3y = 12
3x + 2y = 6
use the elimination method (definition at the bottom of the page)
multiply both sides of the equation 4x - 3y = 12 by 2
8x - 6y = 24
multiply both sides of the equation 3x + 2y = 6 by 3
9x + 6y = 18
now, add the two equations:
17x = 42
x = 42/17
now, plug this into the equation 3x + 2y = 6
126/17 + 2y = 6
2y = -24/17
y = -12/17
A biologist wants to compare the proportions of rainbow trout infected with whirling disease (an illness of
trout and salmon caused by a microscopic parasite) coming from two separate watersheds. For each
watershed, the biologist will collect a random sample of trout and record the proportion infected in the
sample. The biologist intends to estimate the difference for all trout in the two watersheds. Assuming all
conditions for inference are met, which of the following is the most appropriate method for the biologist to
use to analyze the results?
A
A one-sample z-interval for a population proportion
B
A one-sample z-interval for a sample proportion
с
A one-sample z-interval for a difference in sample proportions
D
A two-sample z-interval for a difference in population proportions
E
A two-sample z-interval for a difference in sample proportions
Answer:
D
Step-by-step explanation:
Because, the biologist wants to find the difference between the population of trouts from two watershed,

Step-by-step explanation:
Given
[tex]AO = 5x - 1[/tex]
[tex]BO = 4x + 9[/tex]
Required:
The length of the diagonal
Since AO and BO are diagonals that meets at O, we have:

What is the area of this parallelogram
Answer:
B. 12.25
Step-by-step explanation:
A=bxh=3.5·3.5=12.25
Answer:
17.15
Step-by-step explanation:
There are 2 ways to solve this.
One way is this:
Add 1.4 and 3.5 together to get the total length of the parallelogram. The sum would be 4.9. Then multiply this number by the height of the figure(3.5cm). So that the product of 4.9 and 3.5 is 17.15.
The second way is this:
Find the area of the two triangles and the square and then add those products together. So add:
1.4 x 3.5 ÷21.4 x 3.5 ÷23.5 x 3.5So solve this equation and you will get:
2.45 + 2.45 + 12.25=17.15(6x + 6) + (-3 - 4x)
