Answer:
3x² + 3x³ - x + 8
Step-by-step explanation:
All we have to do is add the terms together
(open parentheses as well)
3x² - 8x + 2 + 3x³ +7x +6
now, simplify
3x²+3x³-x+8
Help me. My pet rat....er my sister needs help with 6th grade work.
Answer:
A
Step-by-step explanation:
Because if your going to divide a whole the whole number needs to be 3/1 so it A the mistake
Answer:
A.) Step 1
Step-by-step explanation:
The actual answer is g=4.
Trevor screwed up at Step 1.
His answer (g = 4/9) to Step 1 (g/3 ⋅ 3 = 4/3 ⋅ 1/3 ) is correct, but it's not the correct answer for g/3 = 4/3.
In Step 1, Trevor's equation was accurate, until the last number (1/3).
If he had flipped 1/3 to 3/1, he would've been correct.
g/3 ⋅ 3 = 4/3 ⋅ 1/3 ← MISTAKE.
Hope this helps out your pet ra- I mean sister.

Write an
explicit formula for An, the nth term of the sequence 32, 25, 18, ....
Answer:
[tex]\bold{a_n=-7n+39}[/tex]Step-by-step explanation:
25 - 32 = -7 and 18 - 25 = -7
It means an arithmetic sequence with common difference d = -7
[tex]a_n = a_1+d(n-1)\\\\a_1=32\\d=-7\\\\a_n=32+(-7)(n-1)\\\\a_n = 32-7n+7\\\\\underline{a_n=-7n+39}[/tex]

find the x and y intercepts of the graph -6x + 4y = 32 state your answers as while numbers or as improper fractions in simplest form
Answer:
x intercept = -5.33
y intercept = 8
Step-by-step explanation:
The given equation is ,
⇒ -6x + 4y = 32 ,
The standard form of the Intercept form is ,
⇒ x/a + y/b = 1 , where
a is x interceptb is y intercept .• Converting the equation :-
⇒ 2( -3x + 2y ) = 32
⇒ -3x + 2y = 16
⇒ -3x + 2y / 16 = 1
⇒ (-3x)/16 + 2y/16 = 1
⇒ -3x/16 + y/8 = 1
Convert -3x/16 in x/a form⇒ x/-5.33 + y/8 = 1 .
Therefore ,
x intercept = -5.33 y intercept = 8Ten members of Balin’s soccer team ran warm ups for practice. Each member ran the same distance. Their combined distance was StartFraction 5 Over 6 EndFraction of a mile. To find the distance that each member ran, Balin wrote the expression below.
Answer:
Each member ran (1/12) of a mile.
Step-by-step explanation:
We have 10 members of Balin's soccer team.
Each one of them ran a distance D.
We know that their combined distance was 5/6 of a mile.
And if each one of them ran the same distance D, then the combined distance is ten times D, or :
10*D
and this is equal to 5/6 of a mile, then we get the equation:
10*D = (5/6) of a mile.
We want to solve this for D, so we can divide both sides by 10:
10*D/10 = (5/6)/10 of a mile.
D = (5/10*6) of a mile
D = (5/10)/6 of a mile
D = (1/2)/6 of a mile
D = (1/2*6) of a mile
D = (1/12) of a mile.
This means that each member ran (1/12) of a mile.

What is the area of the shaded region in the given circle in terms of pi and in simplest form?
A) (120pi + 6 sqrt 3) m^2
B) (96pi + 36 sqrt 3) m^2
C) (120pi + 36 sqrt 3) m^2
D) (96pi + 6 sqrt 3) m^2
Answer:
Area of the shaded portion = (120π + 36√3)sq. m
Step-by-step explanation:
Area of the shaded region = Area of circle - Area of triangle
Given
radius of the circle = 12m
Area of the circle = πr²
Area of the circle = π(12)²
Area of the circle = 144π m²
Area of the sector = theta/360 * πr²
Area of the sector = 60/360 * 12²π
Area of the sector = 60/360 * 144π = 24π
Area of the triangle = 1/2 bh
Area of the triangle = 1/2 (12cos30)(12)
Area of the triangle = 36√3
Area of the shaded portion = (144π - 24π + 36√3)sq. m
Area of the shaded portion = (120π + 36√3)sq. m
The measures of the angles in an equilateral triangle are equal.
What is the measure of each angle of an equilateral triangle?
O A. 30?
B. 45?
C. 60?
O
D. 90?
O
Answer:
C. 60°
Step-by-step explanation:
because all angles in a triangle sum up to 180°
60°+60°+60°=180°

What is the product of 5/6 * 18/30? Be sure to simplify your answer.
The answer is 113/30.
break down how you get the answer 113/30
please dont use files
Answer:
1/2
Step-by-step explanation:
To multiply fractions, you multiply numerator with numerator and denominator with denominator:
a/b*c/d=(a*c)/(b*d)
5/6*18/30=(5*18)/(6*30)=90/180=9/18=1/2
Therefore, the answer is 1/2. Looks like your answer of 113/30 either is wrong or the problem was not formatted correctly.
A car dealership pays a wholesale price of $12,000 to purchase a vehicle. The car dealership wants to make 34% profit. What is the mark up and retail price.
Answer:
$16080
Step-by-step explanation:
Given data
Wholesale price = $12,000
Profit = 34%
Let us find 34% of $12,000
=34/100*12000
=0.34*12000
=$4080
Hence the markup price is $4080
And the retail price is
=4080+12000
=$16080

Tom is told by his doctor that he needs to lose 15 pounds if Tom now it's 285 pounds then by what percentage should Tom's week decrease
Answer:
the percentage is 5.56%
Step-by-step explanation:
The computation of the percentage that the tom should decrease is shown below:
As Doctor said tom to reduce 15 pounds
As of now the tom has 285 pounds
So after considering the 15 pounds, it would be
= 285 - 15
= 270 pounds
Now the percentage that should be considered is
= (285 - 270) ÷ (270)
= 5.56%
Hence, the percentage is 5.56%

Solve the Following Questions. (show your work)
Part A.) A planet’s diameter is approximately 27,340,000 meters. What is that number in scientific notation?
Part B.) What is the product of 3.20 × 10–5 and 6.5 × 103?
Answer:
A = 2.734*10^7, B = .208
Step-by-step explanation:
A = 2.734*10^7
There are 7 decimal places from 0 to 10 million
B = .208
multiply 3.2 and 6.5, get 20.8, 10^3 * 10^-5 =10^-2
20.8 * 10^-2 = .208
