Find and simplify an expression for the area of three rows of m squares with side lengths of m centimeters .
The area is __ square centimeters.
Answer:
The area of the shape is 3m³ square centimetres.
Step-by-step explanation:
We know that the area of single square is m² cm².
There are m squares per row, so for the area of the row, we multiply that by m, giving us m³ cm².
Finally, we know that there are three rows, so we need to multiply that by three, giving a total area of 3m³ cm²

An artist buys 36 tubes of oil paint, 6 paintbrushes, 3 canvases, and 2 jars of paint thinner. What is the ratio of paintbrushes to tubes of oil paint?
What is the correct answer?
Answer:
C. [tex]\sqrt{3x^2+21x}[/tex]
Step-by-step explanation:
When one multiplies two radicles, one multiplies each term in the radical by the term in the other radical, then one simplifies the result and puts the radical sign over the result. If there are any perfect squares one will take the terms out. In this scenario, such is not the case.
[tex]\sqrt{3x}*\sqrt{x+7}\\\\\sqrt{3x(x+7)}\\\\\sqrt{3x^2+21x}[/tex]
Express 2 x 2 x 2 x 2 x 2 in index notation.
Given:
The expression is
[tex]2\times 2\times 2\times 2\times 2[/tex]
To find:
The index notation of the given expression.

Find a polynomial with integer coefficients that satisfies the given conditions. Q has degree 3 and zeros −6 and 1 + i.
Answer:
[tex]Q(x) = x^3 + 4x^2 - 10x + 12[/tex]
Step-by-step explanation:
Complex numbers:
The most important relation when dealing with complex numbers is that:
[tex]i^2 = -1[/tex]
Zeros of a function:
Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.
Q has degree 3 and zeros −6 and 1 + i.
Complex roots are always complex-conjugate, which means that if 1 + i is a root, 1 - i is also a root.
I am going to say that the leading coefficient is 1. So
[tex]Q(x) = (x - (-6))(x - (1 + i))(x - (1 - i)) = (x + 6)(x^2 - x(1-i) - x(1+i) + (1+i)(1-i)) = (x + 6)(x^2 - 2x + 1 - i^2) = (x + 6)(x^2 - 2x + 1 - (-1)) = (x + 6)(x^2 - 2x + 2) = x^3 + 6x^2 - 2x^2 - 12x + 2x + 12 = x^3 + 4x^2 - 10x + 12[/tex]
The polynomial is:
[tex]Q(x) = x^3 + 4x^2 - 10x + 12[/tex]
A town has a population of 13000 and grows at 2.5% every year. What will be the population after 5 years, to the nearest whole number?
The population of the town after 5 years will be 147089 (approx).
Step-by-step explanation:
The exponential growth equation is given by :-
f(x)=A(1+r)^x...(*)
, where A = initial population , r= rate of growth ( in decimal) and x is time.
As per given , we have
A= 13000
r=2.5%=0.025
x= 5 years
Using (*), the population of the town after 5 years would be :
f(5)=13000(1+0.025)^5=13000(1.025)^5\\\\=13000(1.13140821289)=14708.306767614708.3067676\approx147089
Hence, the population of the town after 5 years will be 147089 (approx).
Janelle spots some dolphins in the ocean. Her father draws a diagram to show how far down they can go. How far is this relative to sea level? What would an altimeter read at this depth?
The diagram is missing, so i have attached it.
Answer:
-1000 ft
Step-by-step explanation:
From the diagram attached, we see that they went 1000 ft below the sea level.
Now an altimeter is used to measure altitude depth of an object relative to a fixed level which in this case the fixed level is the top of sea. Since the depth in this case is below sea level, it will be negative.
Thus,the altimeter will read -1000 ft
Answer:
The dolphins are shown 1,000 feet below sea level. The altimeter reading would be -1,000 feet.

Answer:
Final answer: x=0 m:3 and x=-6 m:2
Step-by-step explanation:
1. 4x³(x²+12x+36)- Divide by greatest common factor, to simplify.
2. 4x³(x+6)(x+6)- Factored
3. 4x³ = 0 Set each factor equal to zero
4. x+6=0 x+6=0
So, x= -6, two times, mulitiplicity 2
So, 4x³=0, so x=0 three times, mulitiplicity 3
Final answer: x=0 m:3 and x=-6 m:2

Algebra please solve 7(2x - 3y) + 4(3y - 5x) =
Answer:
-8x-9y
Step-by-step explanation:
Hey There!
So basically this problem is asking you to simplify this expression using distributive property
The first step would be to distribute 7 into what is inside the parenthesis (2x and -3y)
2x*7=14x
-3y*7=-21y
so now we have 14x-21y + 4(3y-5x)
the next step would be to distribute 4 to what is inside the parenthesis (3y and -5x)
4*3y=12y
4*-5x=-20x
so now we have 12x-21y-20x+12y
the final step is to combine like terms
12x-20x=-8x
-21y+12y=-9y
so the simplified version of 7(2x - 3y) + 4(3y - 5x) is -8x-9y
Answer:
14x-21y+12y-20x. 14x-20x+12y-21y. -6x-9y
100% of what number is 27? Provide an exact fraction answer
Answer:
Your answer is 27
I hope I helped, would appreciate brainliest! ;)
Step-by-step explanation:
'Percent (%)' means 'out of one hundred':
27% = 27 'out of one hundred',
p% is read p 'percent',
27% = 27/100 = 27 ÷ 100
Calculate percentage:
'Percentage' is obtained by multiplying 100 by 27%
27% of 100 is equivalent to multiplying them:
27% × 100 = ?
27% × 100 =
(27 ÷ 100) × 100 =
(27 × 100) ÷ 100 =
2,700 ÷ 100 =
27
Proof.
How do we check the result?
If 27% × 100 = 27 =>
Divide 27 by 100...
... And see if we get as a result: 27%
Note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
n/100 = n%, any number.
Calculate the percent value:
27 ÷ 100 =
0.27 =
0.27 × 100/100 =
(0.27 × 100)/100 =
27/100 =
27%
So we have proved that the calculations are correct.
Answer:
Percentage of

The square of a number 60 greater than half of the number. Form a
quadratic equation and solve to determine the possible values of the
number.
Answer:
The number could be [tex]-7.5[/tex] or [tex]8[/tex].
Step-by-step explanation:
I'm going to assume this means "The square of a number is 60 greater than half of the number." Let the number be [tex]x[/tex]. The square of [tex]x[/tex] will be [tex]x^{2}[/tex]. "is" denotes that we use the "[tex]=[/tex]" sign, so our equation so far is [tex]x^{2} =[/tex] . Half of [tex]x[/tex] is [tex]\frac{1}{2}x[/tex], and "greater than" implies addition, so [tex]60[/tex] greater than [tex]\frac{1}{2}x[/tex] is [tex]\frac{1}{2}x+60[/tex]. Therefore, the equation is [tex]x^{2} =\frac{1}{2}x+60[/tex].
Solving for [tex]x[/tex], we get:
[tex]x^{2} =\frac{1}{2}x+60[/tex]
[tex]2x^{2} =x+120[/tex] (Multiply both sides of the equation by [tex]2[/tex] to get rid of the fraction)
[tex]2x^{2} -x-120=0[/tex] (Subtract [tex]x+120[/tex] from both sides of the equation to make it easier to solve)
[tex]2x^{2} +15x-16x-120=0[/tex] (Split [tex]-x[/tex] into [tex]15x-16x[/tex] to make the LHS easier to factor)
[tex]x(2x+15)-8(2x+15)=0[/tex] (Take a common factor out of the first two terms and the last two terms)
[tex](2x+15)(x-8)=0[/tex] (Take another common factor out)
[tex]2x+15=0,x-8=0[/tex] (Zero Product Property)
[tex]x=-7.5,8[/tex] (Solve)

Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 500 = 900
Answer:
Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 500 = 900
Step-by-step explanation:
Rounding to the nearest hundred means rounding 271 to 300 and 550 to 600.
Think of it as
271 changes to 0.271
The 7 would be in the hundredths place.
7 is greater than 5; therefore, round up.
Now you have 0.3, change this back to it's normal decimal places to get 300.
550 changes to 0.550
Where the second 5 would be in the hundredths place.
5 is equal to 5; therefore, round up.
Now you have 0.6, change this back to it's normal decimal places to get 600.
Mark rounded to the nearest place which is not the same.

Find the value of 3y + 4 given that - 2y + 6 = 2.
Simplify your answer as much as possible.
Answer:
10
Step-by-step explanation:
to find the answer for 3y + 4 we have to find the value of y.
we can find that by using the second equation.
-2y+6=2
-2y+6-2 =0 (subtract 2 from both the sided)
4= 2y (we will bring the -2y to the other side of the equation and then subtract the 6-2 to get the 4)
4/2=y (divide by 2 on both the sides)
∴ y=2
now we will plug in the y of value that we see as -2 into the first equation.
∴ 3y+4 will become
= 3(2)+4
=6+4
=10
hope this helps!!
