Answer -2x^4 - 2x^3 + 22x^2 - 30x + 12
Here's your solution
=> (2x^2 - 4x + 2) - (x^2 + 3x - 6)
=> (2x^2 - 4x + 2) -x^2 - 3x + 6
=> firstly multiple whole with -x^2
=> -x^2(2x^2 - 4x + 2) = -2x^4 + 4x^3 - 2x^2
=> now with -3x
=> -3x(2x^2 - 4x + 2) = -6x^3 +12x^2 -6x
=> with 6
=> 6(2x^2 - 4x + 2) = 12x^2 - 24x + 12
=> now add all terms
=> -2x^4 - 2x^3 + 22x^2 - 30x + 12
hope it helps and your day will be full of happiness ^_^

c)80degree
d)90degree
Answer:
∠ PTQ = 70°
Step-by-step explanation:
The angles subtended by the radii and tangents to the circle , sum to 180°
∠ PTQ + 110° = 180° ( subtract 110° from both sides )
∠ PTQ = 70°

Answer:
v = 3√6
u = 6√3
Step-by-step explanation:
v = 3√6 because it is an isosceles triangle
u² = 2(3√6)²
u² = 108
u =√108 = 6√3
Jake washes cars. On monday he washed 18 cars for $90. On tuesday he washed 9 cars for $45. On wednesday he washed 12 cars for $60. What is the rate of change of Jakes earnings?
Answer:
the rate of change is 5
Step-by-step explanation:
$90 / 18 cars = $5 per car
$45 / 9 cars = $5 per car
$60 / 12 cars = $5 per car
That means the rate of change is 5 (5/1)

Find the solution to the following system of equations using the comparison method:
Y=8x
Y=10x -6
No links or I am reporting
Answer:
4 I think is the answer
Step-by-step explanation:
Suppose that y varies directly with x and y=20 , when x =8
a : write a direct variation equation that relates x and y ??
b : find y when x =3 ??
Answer:
y = 7.5
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 20 when x = 8
20 = 8k ( divide both sides by 8 )
2.5 = k
(a)
y = 2.5x ← equation of variation
(b)
When x = 3 , then
y = 2.5 × 3 = 7.5
A bag contains 8 red M&Ms, 13 blue M&Ms, 4 brown M&Ms, and 8 green M&Ms. An M&M is picked at random from the bag. What is the probability of picking: A Red M&M:
Given:
Number of red M&Ms = 8
Number of blue M&Ms = 13
Number of brown M&Ms = 4
Number of green M&Ms = 8
An M&M is picked at random from the bag.
To find:
The probability of picking a red M&M.
Solution:
We have,
Number of red M&Ms = 8
Total number of M&Ms [tex]= 8+13+4+8[/tex]
[tex]=33[/tex]
So, probability of picking a red M&M is:
[tex]\text{Probability}=\dfrac{\text{Number of red M&Ms}}{\text{Total number of M&Ms}}[/tex]
[tex]\text{Probability}=\dfrac{8}{33}[/tex]
Therefore, the probability of picking a red M&M is [tex]\dfrac{8}{33}[/tex].

(-a)n is negative
If a is a real number and n is a positive integer, which of the following represents all values of a and n such that the above
statement is true?
A. {a | a is positive) and {n | n is even}
B. {a | a is negative } and for {n| n is odd}
C. {a | a is negative} and {n | n is even}
D. {a | a is positive} and {n | n is odd}
Answer:
(-a)n is negative number, and since you did not provide a clear first option, I will assume the answer is none of the above. However, the accurate answer is C
Step-by-step explanation:
how do you solve this??
Answer:
The sum of this entire line is 180, so to solve this we would subtract 20 from 180, which means x = 160.

2. If all the letters in the word ENVELOPE are randomly rearranged, what is the probability the letters will
spell the word ENVELOPE?
A.
3/28
B.
1/720
c.
1/1120
D.
1/6720
The probability the letters will spell the word ENVELOPE is 1/6720 option (D) 1/6720 is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
If all the letters in the word ENVELOPE are randomly rearranged,
As we know, a permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
From the definition of the permutation and combination we can calculate the total number of arrangements:
E :: 3
N :: 1
V :: 1
L :: 1
O :: 1
P :: 1
The arrangement Letters:
E,L,N,O,P,V
Total Number of Letters:
8
Total Number of Unique Letters:
6
Total arrangements = 8!/3!
Total arrangements = 8×7×6×5×4
Arrangements = 6720
Total number of outcomes = 6720
Number of favorable outcomes = 1
Probability = 1/6720
Thus, the probability the letters will spell the word ENVELOPE is 1/6720 option (D) 1/6720 is correct.

HELP NO DECIMAL ANSWERS OR YOU WILL BE REPORTED!!!!!!
Answer:
112 inches I believe! I hope this helps!
Step-by-step explanation:
Answer:
2004 cubic inches
Step-by-step explanation:
Looking at the figure, there seems to be a chunk missing from the front. Since the overall length is 15 inches, and the length near the missing chunk is 12, then the missing length is 3. If that chunk was filled in, this would have been a 17 * 15 * 8 rectangluar prism. That would have been 2040 cubic inches. (120 * 17) However, a 3 by 8 by 3 triangular prism is missing.
1/2(3 * 8 * 3)
1/2(24 * 3)
1/2(72)
36
Now, subtract 36 from 2040.
2040 - 36
2004 cubic inches

The circumference of a circle is 6π m. What is the area, in square meters? Express your answer in terms of \piπ.
Answer:
Area = 9π sq. m.
Step-by-step explanation:
C = πd
6π = πd
d = 6
r = 3
A = π[tex]r^{2}[/tex] = π[tex]3^{2}[/tex] = 9π sq. m.
A sound wave is traveling at 6,420m/s and has a frequency of 600Hz. What is the wavelength?
Answer:
10.7 m
Step-by-step explanation:
Given that,
The speed of a sound wave, v = 6,420 m/s
The frequency of the wave, f = 600 Hz
We need to find the wavelength of the wave. We can find it using the below relation as follows :
[tex]v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{6420}{600}\\\\\lambda=10.7\ m[/tex]
So, the wavelength of the sound wave is equal to 10.7 m.

How many solutions does this equation have?
–2 + 2s = –3s + 8
Answer:
Step-by-step explanation:
-2 + 2s = - 3s + 8
-2 - 8 = - 3s - 2s
-10 = - 5s
-10/-5 = s
2 = s
Answer:
2
Step-by-step explanation:
-2+2s=-3s+8
-2+2s-(-3s)=8
-2+2s+3s=8
-2+5s=8
5s=8-(-2)
5s=8+2
5s=10
s=10/5
s=2

Let X and Y be the following sets: X = {0, 12, 23} Y = {3, 12, 15) Which of the following is the set X/Y?
Answer:
set X/Y = {0,23}
Step-by-step explanation:
We are given the sets;
X = {0, 12, 23}
Y = {3, 12, 15}
Now, we want to find the set X/Y.
The set X/Y means the set that has numbers which are only in set X but not in set Y.
The numbers from inspection of both sets are 0 and 23.
Thus;
set X/Y = {0,23}
