Factor completely: 2x^3-12x^2+18x
Answer:
2x(x - 3)²
Step-by-step explanation:
We can simplify this a lot by first factoring 2x out of each term:
2x³ - 12x² + 18x
= 2x(x² - 6 + 9)
We can then factor the trinomial fairly easily, as it's a perfect square:
= 2x(x - 3)²
Find the solution to the equation.

2. no
3. yes
4.yes
Step-by-step explanation:
hope this helped
Answer:
No, No, Yes, Yes
Step-by-step explanation:
We can simply substitute the pairs as x and y in the equation:
(5, 0)
7*5 + 5*0 = 35 + 0 = 35
[tex]35 \ne 9[/tex]
(-4, -3)
7*(-4) + 5*(-3) = -28 - 15 = -43
[tex]-43 \ne 9[/tex]
(2, -1)
7*2 + 5*(-1) = 14 - 5 = 9
[tex]9 =9[/tex]
(-3, 6)
7*(-3) + 5*6 = -21 + 30 = 9
[tex]9 = 9[/tex]

Which of these are characteristics of reptiles? Check all that apply. They undergo internal fertilization. Their urine is concentrated. They use their skin for gas exchange. They have two-chambered hearts. They are covered in scales.
Answer:
Answers Below. Have a wonderful day!
Step-by-step explanation:
They undergo internal fertilization: True Most reptiles undergo internal fertilization sexually when the sperm of a male reptile enters the cloaca of female reptiles, fertilizing the egg.
Their urine is concentrated: False Reptiles do not have the ability to produce liquid urine that is more concentrated than their own body fluid because they lack a structure in their nephron called the Loop of Henle.
They use their skin for gas exchange: False They cannot use their skin as an organ of gas exchange. Reptiles depend entirely on their lungs for this.
They have two-chambered hearts: False They have three-chambered hearts.
They are covered in scales: True All reptiles are covered in scales (snakes, lizards, turtles, etc.)

Answer:
43x+39
Step-by-step explanation:
(5)(9x)+(5)(6)+−2x+9
=45x+30+−2x+9
=45x+30+−2x+9
=(45x+−2x)+(30+9)
=43x+39
(if this helps please give brainliest and 5 stars thanks)
Answer:
43x + 39
Step-by-step explanation:
5 ( 9x + 6 ) - 2x + 9
Firstly, open up the brackets.
= 45x + 30 - 2x + 9
Now bring the like term together and simplify.
=45x - 2x + 30 + 9
= 43x + 39
To purchase $14,500 worth of restaurant equipment for his business, Hans made a down payment of $1800 and took out a business loan for the rest. After years of paying monthly payments of $562.88. , he finally paid off the loan.
Answer:
hello your question is incomplete below is the complete question
To purchase $14,500 worth of restaurant equipment for his business, Hans made a down payment of $1800 and took out a business loan for the rest. After 2 years of paying monthly payments of $562.88. , he finally paid off the loan. What was the total amount Dean ended up paying for the equipment ( including the down payment and monthly payments )
answer: $15309.12
Step-by-step explanation:
Initial cost of equipment = $14500
Down payment = $1800
cost of equipment = 14500 - 1800 = $12700
Monthly payment = $562.88
Therefore payment made after 2 years = ( 562.88 * 24 ) = $13509.12
Total amount paid by Dean for the equipment
= down payment + monthly payments
= $1800 + $13509.12
= $15309.12

Gabriel has 15 ⅝ pounds of clay. He will use 7/10 pound to make each bowl. After making 8 bowls, Gabriel wonders how many more bowls he can make. How many more bowls can how make?
Answer:
14
Step-by-step explanation:
The total amount of bowls he can make given the pounds of clay and the pound needed to make a bowl = [tex]15\frac{5}{8}[/tex] ÷ [tex]\frac{7}{10}[/tex]
= [tex]\frac{125}{8}[/tex] ÷ [tex]\frac{7}{10}[/tex]
= [tex]\frac{125}{8}[/tex] ×[tex]\frac{10}{7}[/tex] = 22.32
Number of bowls he can more more = total amount of bowls that can be made - number of bowls already made
22.32 - 8 = 14.32 bowls
Rounding off to the nearest whole number gives 14
what is the area of this figure
Answer:
174.5m
Step-by-step explanation:
So we have to break the shapes down to triangle, rectangle and the small rectangle
Area of rectangle=WxL
Area of triangle= (BxH)÷2
triangle=
(23x11)÷2
=253÷2
=126.5m
rectangle=
9x19
=28m
square#2(the small one)=
5x4
=20m
All:
20+28+126.5
=174.5m
YO 10 or 22 points can somebody pls help me I’m stuck. Solve each inequality for x then graph your answer on a number line. Remember when you divide by a negative you have to switch the inequality symbol. Pls pls help me :(
Answer:
x<5
Step-by-step explanation:
−2(x−7)>4
Step 1: Simplify both sides of the inequality.
−2x+14>4
Step 2: Subtract 14 from both sides.
−2x+14−14>4−14
−2x>−10
Step 3: Divide both sides by -2.
−2x ÷ −2 > −10 ÷ −2
x<5

Lannister checks out 6 set of books from the library each set has the same number of books she reads 7 of the books and she has 11 books left to read how many books are in each sets
Answer:
3
Step-by-step explanation:
Lannister checks out 6 sets of book
Each set had the same number of books
She reads 7 books and has 11 more to go
Therefore the number of books in each set can be calculated as follows
= 11+7
= 18
18/6
= 3
Hence there are 3 books in each set

2{x+8}+5{x-1}=60 answer
Answer:
x=7
Step-by-step explanation:
2{x+8}+5{x-1}=60
Distribute
2x+16+5x-5 = 60
Combine like terms
7x +11 = 60
Subtract 11 from each side
7x+11-11 = 60-11
7x = 49
Divide each side by 7
7x/7 = 49/7
x = 7

Answer:
You can always ask the tutor they give the correct answer :))
what's the domain and range function for y=(x-12)^2+11
Answer:y = x 2 − 12 x The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation: ( − ∞ , ∞ ) Set-Builder Notation: { x | x ∈ R } The range is the set of all valid y values. Use the graph to find the range. Interval Notation: [ − 36 , ∞ ) Set-Builder Notation: { y | y ≥ − 36 } Determine the domain and range. Domain: ( − ∞ , ∞ ) , { x | x ∈ R } Range: [ − 36 , ∞ ) , { y | y ≥ − 36 }
Step-by-step explanation:
Answer:
Step-by-step explanation:
There is no restriction upon x so the domain is all real numbers
x=(-oo, +oo)
y has a minimum value when x=12 and y=11. Any other value of x increases the value of y. So the range is all real numbers greater than or equal to 11.
y=[11, +oo)
