The length and breadth of a retanlge are (2x+y) cm (x+2y)cm respectively. Find its area.
Answer:
2x^2+5xy+2y^2
Step-by-step explanation:
Area = l*b
Area = (2x+y)*(x+2y)
Area = 2x^2+5xy+2y^2

Help! write the set of numbers in set-builder notation: the set of all real numbers except 100
Answer:
Step-by-step explanation:
The set of all real numbers except for 100 in set builder notation (assuming the variable is x) is:
The very first x represents the variable.
The second with the R represents the number. Here, we want all real numbers.
And the third is the constraint. We want all real numbers except for 100.
Answer:
{ x | x ∈ R, x ≠ 100 }
Step-by-step explanation:
Real numbers (R) include all rational and irrational numbers.
Hence, If we need to write it in set-builder notation, we will write as:
{ x | x ∈ R, x ≠ 100 }
In words : "x such that x belongs to R, x is not equal to 100"
This shows that x is any real number except for 100.

Step-by-step explanation:
1.) two tails :
total no. of outcomes possible is TT,TH,HT,HH
no. of outcomes with TT is 1
p( tails on both) = 1/4
2.) tails at least one:
no. of outcomes with one tails atleast is 3 (TT,th,ht,)
p( atelast one tails) = 3/4
3.) tails on one
no. of outcomes with one tails at most is 2 (th,ht)
p( atmost one tails) is 2/4= 1/2
4. no tails
no. of outcomes with no tails is 1(HH)
p( no tails) = 1/4
hope it's understandable.
Answer:
1.) two tails :
total no. of outcomes possible is TT,TH,HT,HH
no. of outcomes with TT is 1
p(tails on both) = 1/4
2.) tails at least one:

p(atelast one tails) = 3/4
3.) tails on one

4. no tails
no. of outcomes with no tails is 1(HH)
p(no tails) = 1/4
Sarah counted the number of tiles at each step and made a table. She explained that the
number of tiles in each figure was always 3 times the step number minus 2.
Create an equation that fits Sarah's way of seeing the relationship.
PLS HELP DUE IN 10 min!!
Answer:
n(number of tiles) x 3 - 2
Step-by-step explanation:
times mean multiplication and minus mean subtraction, I hope this helps.
An equation is formed of two equal expressions. An equation that fits Sarah's way of seeing the relationship is y = 3x - 2.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
As stated by Sarah that "the number of tiles in each figure was always 3 times the step number minus 2", this can be written in the form of an equation as shown below.
Number of tiles = [3 × (Number of steps)] - 2
Assume that the number of tiles is represented by y, while the number of steps can be written as x. Therefore, we can write the equation as,
y = 3x - 2
Now, let's check the equation,
When the number of steps is 3, the number of tiles is 7.
y = 3(3) - 2
y = 9 - 2
y = 7
Since the number of tiles is the same, therefore, the equation is correct.
Hence, an equation that fits Sarah's way of seeing the relationship is y = 3x - 2.

The value of function (h·g)(b) for x=-6 is -867.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given functions are g(b)=5b-9 and h(b)=(b-1)².
Now, (h·g)(b)=h(b)×g(b)
= (b-1)²×5b-9
= (b²-2b+1)×(5b-9)
= b²(5b-9)-2b(5b-9)+1(5b-9)
= 5b³-9b²-10b²+18b+5b-9
= 5b³-10b²+23b-9
Now, (h·g)(-6)
= 5(-6)³-10(-6)²+23(-6)-9
= -1080+360-138-9
= -867
Therefore, the value of function (h·g)(b) for x=-6 is -867.

What is the factored form of this expression x^3+3x^2-6x-18
Answer:
(x + 3) (x^2 - 6)
Step-by-step explanation:
Factor the following:
x^3 + 3 x^2 - 6 x - 18
Factor terms by grouping. x^3 + 3 x^2 - 6 x - 18 = (x^3 + 3 x^2) + (-6 x - 18) = x^2 (x + 3) - 6 (x + 3):
x^2 (x + 3) - 6 (x + 3)
Factor x + 3 from x^2 (x + 3) - 6 (x + 3):
Answer: (x + 3) (x^2 - 6)
A submarine that is already at 605 feet below sea level ascends (rises up) 475 feet before descending (sinking down) another 255 feet.
Answer:
-350ft
Step-by-step explanation:
so basically 605 is negative and 255 is a negative then you add those two then it would be -860 then you subtract the positive 475 and that will equal -350

Perimeter:
PLEASE HELP
Answer:
14x + 4
Step-by-step explanation:
The perimeter of a rectangle is the sum of all its sides. The rectangle have two sides with length 5x + 2, so:
(5x + 2)×2 = 10x + 4
And it also have two sides with length 2x, so:
(2x)×2 = 4x
And now just add it:
10x + 4 + 4x = 14x + 4
Answer: Perimeter = 14x + 4
Concept:
Here, we need to know how to find the perimeter of a rectangle.
Perimeter (rectangle) = 2 (l + w)
l = length
w = width
If you are still confused, you may refer to the attachment below for a graphical explanation.
Solve:
Given information
l = 5x + 2
w = 2x
Given expression
Perimeter = 2 (l + w)
Substitute values into the expression
Perimeter = 2 (5x + 2 + 2x)
Combine like terms
Perimeter = 2 (7x + 2)
Expand parentheses and apply the distributive property
Perimeter = 2 · 7x + 2 · 2
Perimeter = 14x + 4
