Answer:
I'm the smartest person in my math class.
Step-by-step explanation:
While subtracting , the sign of each term of second expression changes & remove the parentheses.
⟶ 5x³-3x +6-2x²+4x-8
Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.
⟶ 5x³-3x+4x+6-8-2x²
⟶ 5x³+x-2-2x²
In standard from , the expression should be written in such a way that the power of variables goes from highest to lowest.
what is 30+11x-12-6x
Write an explicit formula for the nth term of this sequence:
6, 11, 16, 21, . . .
1. an=5n+11
2. an=5n+1
3. an=21-5n
4. an=6n+1
Answer:
2)an = 5n + 1
Step-by-step explanation:
This is an arithmetic series.
6 , 11 , 16, 21 ,.....
First term = [tex]a_{1}[/tex] = 6
Common difference = d = second term - first term
= 11 - 6 = 5
nth term = [tex]a_{1}+(n-1)*d[/tex]
= 6 + (n - 1) * 5
= 6 + n * 5 - 1*5
= 6 +5n - 5
= 6 - 5 + 5n
= 1 + 5n
Which expression is the result of factoring the expression below by taking out its greatest common factor?
8x2 – 24 = ?
Answer:
Step-by-step explanation:
You need to give us the choices. However, I will try and give you the answer.
The highest common factor is 8
8(x^2 - 3) This is the answer I think the question expects.
8(x - √3 )(x + √3) this is also possible

Ms. Meyer washed
2/7
of her laundry. Her son washed
1/4
of it. Who washed most of the laundry? How much of the laundry still needs to be washed?
Solve this on paper. Then check your work on Zearn.
write your answer as a fraction ill mark you !
Answer:
15/28 loads of laundry needs to be washed.
Step-by-step explanation:
2/7 + 1/4
=
2 × 4 + 1 × 7
7 × 4 + 4 × 7
=
8/28 + 7/28
=
8 + 7/ 28
=
15/28

What’s the answer for this one??
Answer:
It is the second one.
Step-by-step explanation:
a and e are equal because they are mirrored. d and b are equal because they are on the same line and at the same point where the parallel lines go through. b and f are also mirrored. That leaves c and e which don't match.

If cos θ > 0, which quadrant(s) could the terminal side of θ lie?
Answer:
I and IV
Step-by-step explanation:
cosine is positive/greater than 0 in quadrants I and IV. Its just a rule of the unit circle.
Can remember by All Star Trig Class
meaning all the trig funtions are positive in quadrant I
sin is positive in II
tan is positive in III
and cos is positive in IV
Melissa earns $180 a week selling shoes plus a commission of $10 each pair of shoes she sells. How
many pairs of shoes must she sell to make a minimum of $500 a week?
Step-by-step explanation:
10X+ 180= 500
10X= 500-180
10X= 320. .....divine both sides by 10 to solve for X
X = 32.
check
10(32)+180 = 500
320+180 =500
500 =500...confirmed
-14 = 4x - 2
what is the x ?
Answer:
X = -3
Step-by-step explanation:
solve for x...................................................................................
Answer:
x = 36°
Step-by-step explanation:
x + 20° + 4x = 200° { exterior angle of a triangle is equal to the sum of two opposite interior angles }
5x = 200° - 20°
5x = 180°
x = 180° / 5
x = 36°

calculate 97% of 345m
Answer:
334.65 meters
Step-by-step explanation:
Solution for What is 97 percent of 345:
97 percent *345 =
(97:100)*345 =
(97*345):100 =
33465:100 = 334.65
Now we have: 97 percent of 345 = 334.65
Answer:
334.65

3(-4+4)+5n=2n what are the steps for finding n
Answer:
1. Move the variables to one side: 3(-4+4) = -3n
2. Distribute. You will end up with 0 = -3n
3. Divide both sides by -3. n = 0
Step-by-step explanation:
Answer:
n=0
Step-by-step explanation:
3(-4+4)+5n=2n
first distribute
-12+12+5n=2n
combine like terms
5n=2n
subtract 2n on both sides
3n=0
divide by 3 on both sides
n=0/3
which is also equal to
n=0

Can someone please help me? 3t + 7 = -8
Answer:
Step-by-step explanation:
Look at 3%2At%2B7=%28+-8+%29.
Moved these terms to the left %28 +8+ %29
It becomes 3%2At%2B7%2B _green%28+8+%29=0.
Look at 3%2At%2B_red%28+7+%29%2_red%28+8+%29=0.
Added fractions or integers together
It becomes 3%2At% 2B % 28+15+%29=0.
Look at highlight_red%28+3%2At%2B15+%29=0.
Solved linear equation %28+3%2At%2B15=0+%29 equivalent to 3*t+15 =0
It becomes highlight_green%28+0+%29=0.
Result: 0=0
This is an equation! Solutions: t=-5.
Answer: t= -1/3
Step-by-step explanation:
3t+7=-8
subtract 7 from 7 and 8 (this cancels out the 7)
left with 3t = -1
divide 3 into 3t and -1
the 3 in 3t is canceled out, leaving us with t, therefore t= -1/3
