Answer: It is a difference of two squares, and it factors to (3x-7)(3x+7)
=============================================================
Explanation:
We can write the 9x^2 as (3x)^2 since
(3x)^2 = (3x)*(3x) = (3*3)*(x*x) = 9x^2
The 49 can be written as 7^2 because 7^2 = 7*7 = 49.
This means 9x^2 - 49 is the same as (3x)^2 - 7^2. We have a difference of two squares.
The difference of squares factoring rule is
a^2 - b^2 = (a-b)(a+b)
which we have a = 3x and b = 7 in this case
So,
a^2 - b^2 = (a-b)(a+b)
(3x)^2 - 7^2 = (3x-7)(3x+7)
9x^2 - 49 = (3x-7)(3x+7)
Side note: This is the same as (3x+7)(3x-7). We can multiply two numbers in any order.

a = 10, b = 24, c = _____
Answer:
c=26
Step-by-step explanation:
By using pythagoram thoerem
c^2=a^2+b^2
c^2=(10)^2+(24)^2
c^2=100+576
c^2=676
c=sqrt(676)
c=26
c=26

Q1 (Describe the two eukaryotic animal cell organelles that have roles similar to the organs of the human digestive system)Q2(Describe how proteins are made packaged and transported within the cell) plz help fast
Step-by-step explanation:
Ans 1
Two eukaryotic animal cell organelles that have roles similar to the organs of the human digestive system are lysosome and mitochondria. ... Mitochondria is like the small intestine, it is responsible for converting the food we eat into nutrients and minerals needed for the cell
Ans2
The Golgi processes proteins made by the endoplasmic reticulum (ER) before sending them out to the cell. ... Proteins must make their way through the stack of intervening cisternae and along the way become modified and packaged for transport to various locations within the cell (Figure 1).
Enter a phrase for the expression
Answer:
The quotient of x and 11.
Step-by-step explanation:
Given:
[tex] \frac{x}{11} [/tex]
Required:
Write the expression in words
Solution:
In the expression given, we have the numerator which is the dividend (x), and the denominator which is the divisor (8).
So, we are dividing x into 8 parts.
A quotient is the result you get when you divide the dividend by the divisor.
✅In describing the expression in words, we would use the following phrase:
The quotient of x and 11.
The dividend is mentioned first before the dividend.

Option 4 is correct
x° + 126° = 180° and value of x is 54°
Step-by-step explanation:
Here, In a given Triangle two sides are equal i.e., Isosceles Triangle.
We know that, in a triangle the sum of all angles Is 180°.
If two sides are equal then also two angles are also equal of that sides.
Now,
63° + 63° + x° = 180°
x° + 126° = 180°
Now, To find the value of x
x° + 126° = 180°
x° = 180° - 126°
x = 54°
Thus, The value of x is 54°
FOR VERIFICATION ONLY:-x° + 126° = 180°
54° + 126° = 180°
180° = 180°
Hence, L.H.S = R.H.S

The double number line shows how far a hummingbird can fly in 1 second.
Answer:
1st box-1
2nd box-3
3rd box-130
Step-by-step explanation:
On the number line, 13 metres is in line with 1 second. So, that means the hummingbird flies 13m/s.
Then to work out the second box, for how much time it takes to travel 39 metres, you would have to do 39÷13=3. This means that in 3 seconds, the hummingbird flies 39 metres in 3 seconds.
To work out how many metres the hummingbird flies in 10 seconds, you would have to do 13×10=130. The reason why you times 13 by 10 is because the hummingbird does 13 metres in 1 second, but we want 10 seconds, so we times it.
Hope this helps :)

Two methods, A and B, are available for teaching a certain industrial skill. The failure rate is 30% for method A and 10% for method B. Method B is more expensive, however, and hence is used only 20% of the time. (Method A is used the other 80% of the time.) A worker is taught the skill by one of the two methods, but he fails to learn it correctly. What is the probability that he was taught by using method A
Answer:
Probability that he was taught by using method A is 14/17
Step-by-step explanation:
Following probabilities are given -
P (F|A) = 0.2
P (F|B) = 0.1
P (A) = 0.7
P (B) = 0.3
Now, P(A|F) = { P (F|A)* P(A)}/{{ P (F|A)* P(A)} + P (F|B)* P(B)}}
P(A|F) = (0.2*0.7)/( (0.2*0.7)+(0.1*0.3)) = 14/17

(x, y) = (8, 4)
Step-by-step explanation:
The relations given in the problem statement let you write two equations. One for the number of shots, and one for the number of points. The variables x and y are defined in the problem statement.
x + y = 12 . . . . . total number of shots
x + 2y = 16 . . . . total number of points
__
These equations are easily plotted by considering their x- and y-intercepts. The x-intercepts of the equations are found when y=0, so are 12 and 16, respectively.
The y-intercepts are found when x=0, so are 12 and 8, respectively. The two lines are shown in the attached. The first is blue; the second is red. Their point of intersection at (x, y) = (8, 4) is circled.

Richard deposits $193.67 every month into his mortgage. At the end of 30 years, he has a balance of $120,182.07. What interest has accrued (been earned) over 30 years?
Answer:
$50,460.87 of interest has been accrued.
Step-by-step explanation:
Richard deposits $193.67 every month into his mortgage.
Each year as 12 months. So after 30 years he will have deposited:
$193.67*12*30 = $69,721.2
At the end of 30 years, he has a balance of $120,182.07. What interest has accrued (been earned) over 30 years?
Interest is total subtracted by deposits. So
120,182.07 - 69,721.2 = $50,460.87
$50,460.87 of interest has been accrued.
