find H.C.F of 2x+4 and x^2-4
Answer:
(x+2)
Step-by-step explanation:
(2x+4) = 2(x+2)
x^2-4 = (x+2)(x-2)
H.C.F = (x+2)
Hope this helped!
Factor each expression separately.
2x + 4 becomes 2(x + 2).
x^2 - 4 becomes (x - 2)(x + 2).
The highest common factor is (x + 2).

If f(x) = (2x + 1)2 – 3 and g(x) = 2(2x2 + 3), which statement is true?
A. f(-5) = g(4)
B. f(3) = g(0)
C. f(1) = g(1)
D. f(-3) = g(-2)
Answer:
d
Step-by-step explanation:
becasuse when you multiply all that stuff since x is the is y fancy way o f saying
From the calculations, we can see that the true statement is f(-3) = g(-2): Option D is correct.
Given the following functions
f(x) = (2x + 1)²– 3 and g(x) = 2(2x² + 3),
According to the last option.
f(-3) = (2(-3) + 1)²– 3
f(-3) = (-6+1)² - 3
f(-3) = (-5)² - 3
f(-3) = 25 - 3
f(-3) = 22
For g(-2)
g(-2) = 2(2x² + 3),
g(-2) = 2(2(-2)² +3)
g(-2) = 2(8+3)
g(-2) = 2(11)
g(-2) = 22
Hence from the calculations, we can see that the true statement is f(-3) = g(-2)

Solve for x: 4 over 5 x + 4 over 3 = 2x x = Write your answer as a fraction in simplest form. Use the "/" symbol for the fraction bar. (2 points)
Answer:
x = 10/9
Step-by-step explanation:
Solve for x:
(4 x)/5 + 4/3 = 2 x
Put each term in (4 x)/5 + 4/3 over the common denominator 15: (4 x)/5 + 4/3 = (12 x)/15 + 20/15:
(12 x)/15 + 20/15 = 2 x
(12 x)/15 + 20/15 = (12 x + 20)/15:
(12 x + 20)/15 = 2 x
Multiply both sides by 15:
(15 (12 x + 20))/15 = 15×2 x
(15 (12 x + 20))/15 = 15/15×(12 x + 20) = 12 x + 20:
12 x + 20 = 15×2 x
15×2 = 30:
12 x + 20 = 30 x
Subtract 30 x from both sides:
(12 x - 30 x) + 20 = 30 x - 30 x
12 x - 30 x = -18 x:
-18 x + 20 = 30 x - 30 x
30 x - 30 x = 0:
20 - 18 x = 0
Subtract 20 from both sides:
(20 - 20) - 18 x = -20
20 - 20 = 0:
-18 x = -20
Divide both sides of -18 x = -20 by -18:
(-18 x)/(-18) = (-20)/(-18)
(-18)/(-18) = 1:
x = (-20)/(-18)
The gcd of 20 and -18 is 2, so (-20)/(-18) = (-(2×10))/(2 (-9)) = 2/2×(-10)/(-9) = (-10)/(-9):
x = (-10)/(-9)
Multiply numerator and denominator of (-10)/(-9) by -1:
Answer: x = 10/9

Step-by-step explanation:
m=y²-y¹/x²-x¹
m=1-5/(-1.5)-0
m=-4/-1.5
m=8/3
y-y=m(x-x1)

A proportional relationship exists between x and y. When x=8 the value of y is 14.
(a) Write an equation for y in terms of x.
Answer:
Equation of y in terms of x is: [tex]y = \frac{7}{4}x[/tex]
Step-by-step explanation:
Proportion means that the change in one quantity causes change in other quantity.
Given that A proportional relationship exists between x and y.
It can be expressed mathematically as:
y ∝ x
When the proportionality symbol is removed, constant of proportionality is introduced which is usually denoted as k
[tex]y = kx[/tex]
Given that y=14 when x=8
Putting in equation
[tex]14 = k * 8\\k =\frac{14}{8}\\k = \frac{7}{4}[/tex]
Putting the value of k in equation
[tex]y = \frac{7}{4}x[/tex]
Hence,
Equation of y in terms of x is: [tex]y = \frac{7}{4}x[/tex]

Paul drank 18.2 ounces of water per day during soccer practice for a total of 54.6 ounces of water. Ryan drank 20.4 ounces of water each day after football practice for a total of 81.6 ounces of water. How many more days of practice did Ryan have than Paul?
A.
They both had the same number of days.
B.
1 day
C.
2 days
D.
3 days
Answer:
B
Step-by-step explanation:
Paul: 54.6/18.2= 3 days
Ryan: 81.6/20.4= 4 days
Answer:
B. 1 day
Step-by-step explanation:
First, we need to find how many days each person practiced for:
Paul- 54.6 ÷ 18.2 = 3
Ryan- 81.6 ÷ 20.4 = 4
4 - 3 = 1, so B is the answer.

(HELP! I HAVE NO TIME) At 2pm, a store had sold 15 packs of toilet paper. By 5pm, the store had sold 57 packs of toilet paper. What is the average rate of change?
[tex]\mathrm {Hey, there!}[/tex]
Let's solve your problem:
The answer would be 280%.
We know the following information:
2pm - 15 toilet paper rolls
5pm - 57 toilet paper rolls
We have to find the percent rate of change.
Here is how we will do this problem:
First, Set up a ratio:
Change in the quantity [15 - 57]
-------------------------------------
Original quantity [15]
57 - 15 = 42
Next, we will divide. the ratio.
Given quantity - 42
Number of packs sold at 2pm - 15
Fraction - 42/15
Convert the fraction to a decimal.
Fraction - 42/15
Decimal - 2.8
Make the decimal to a percent.
Decimal - 2.8
Percent - 28%
Add a zero to the 28.
Our answer is 280%
Answer:
14 packs per hourStep-by-step explanation:
2pm ⇒ sold 15 packs 5pm ⇒ sold 57 packsAverage rate of change = change in sale/ change in time
(57 - 15) / (5 - 2) = 42/3 = 14 packs per hourwhich equation represents the vertical line passing through (7,-3)

Which storm is likely to cause quick destruction along a narrow path?
hurricane
thunderstorm
tornado
Answer:
tornado bc they are narrow and can cause great destruction :) hope I helped !
A tornado is the storm that is likely to cause quick destruction along a narrow path.
What is storm?A storm is any disturbed state of the natural environment or the atmosphere of an astronomical body.
Tornadoes are characterized by their rapidly rotating column of air that extends from the base of a thunderstorm to the ground.
They can cause widespread damage and destruction within a very short period, along a narrow path that can be just a few meters wide.
While hurricanes can produce powerful winds and storm surge that can cause significant damage and destruction, their effects are spread over a larger area, including a broad swath of coastal areas.
Thunderstorms can also produce damaging winds, hail, and flash flooding, but they usually affect smaller areas compared to hurricanes or tornadoes.
Hence, tornado is the storm that is likely to cause quick destruction along a narrow path.
