Choose all answers that apply:
46x - 23 = 46x + 23
-46x + 23 = 46x + 23
46x + 23 = 46x +23
-46x - 23 = 46x + 23
Answers
Answer:
46x + 23 = 46x +23
Step-by-step explanation:
46x - 23 = 46x + 23
Subtract 46x from each side
-23 = 23
This is not true so there are no solutions
-46x + 23 = 46x + 23
Add 46x to each side
23 = 96x +23
Subtract 23 from each side
0 = 96x
x=0 one solution
46x + 23 = 46x +23
Subtract 46x from each side
23 = 23
This is always true so there are infinite solutions
-46x - 23 = 46x + 23
add 46x to each side
-23 = 96x +23
subtract 23 from each side
-46 = 96x
x = -1/2

What is the surface of this square pyramid
Answers
Let’s breakdown this question:
They are asking to find the surface area of this square pyramid. The surface area is the total area of all the faces in the square pyramid. The faces are the base (which is a square) and the four triangles surrounding it.
Let’s look at the areas of all the faces.
Area of the square:
Side x Side
3 x 3
= 9
Area of one triangle:
1/2 x Base x Height
1/2 x 3 x 4
= 1/2 x 12
= 6
There are four triangular faces that make up this square pyramid.
So, area of four triangles
= 4 x (Area of one triangle)
= 4 x (6)
= 24
The total surface area of this triangular pyramid
= (Area of square) + (Area of four triangles)
= (9) + (24)
= 33 ft.^2

Ms lee is handing out wristbands as students enter the dance. There are 40 black , 20 yellow, 25 orange, and 15 purple wristbands, what is the probability that Melanie will get an orange wristband?
Answers
Answer:
[tex] p =\frac{25}{40+20+25+15}= \frac{25}{100}= 0.25[/tex]
So then the probability for this case would be 0.25 or 25%
Step-by-step explanation:
For this case we have 40 black , 20 yellow, 25 orange, and 15 purple wristbands
And we want to find the probability that Melanie will select an orange wristband so we can use the definition of probability:
[tex] p =\frac{successes}{total}[/tex]
And replacing we got:
[tex] p =\frac{25}{40+20+25+15}= \frac{25}{100}= 0.25[/tex]
So then the probability for this case would be 0.25 or 25%

O 2x²(x2 - 1)(2x + 3)
O x2(x + 1)(2x - 3)
O2(x2 - 1)(2x + 3)
Answers
Answer:
the answer is O 2x (x2-1)(2x+ 3)
Answer:
The correct answer is 2x^2(x^2 + 1)(2x - 3)
Step-by-step explanation:
First, you would factor out a single factor out of all of them, which is 2x^2. So, you would have 2x^2 (2x^3 - 3x^2 + 2x - 3) Then, you would use double grouping. When you have double grouped, you will have x^2(2x-3) and 1(2x-3) for the factors. The final factors for that is (x^2 + 1) and (2x - 3), then you would just put 2x^2 in the front to give you the final factorization and the correct answer stated at the top.

What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares whcihh cover a closed figure's surface is its area.
We have, Radius of semicircle = 2 in
So, Area of semicircle = πr²/2
= 3.14/2 x 2/2 x 2 /2
= 1.57 x 1 x 1
= 1.57 mm²
So, the area of the semicircle is 1.57 mm².
Therefore, Radius = 1 in

How does knowing the absolute value of an integer help in determining the distance of two ordered pairs?
Answers
The absolute value helps because when you the absolute value is the the distance of a number away from 0. Meaning that if your finding distance it will never be negative.
Finding the distance between the two is subtracting one of the numbers from each ordered pair from each other. Whether the number is negative or positive, you always turn it, or leave it into a positive number because distance is always positive.

In ABC, A is a right angle. And B = 45 degrees. What is the length of BC
A) 54ft
B) 17√ 3ft
C) 17√ 2ft
D) 17ft
Answers
Given that this is an isosceles triangle (triangle with two congruent sides) and is 45 degrees on both sides then this would be considered a 45-45-90 triangle
The rule for this type of triangle is that going from a congruent side (for example segment AC) to BC would result in your multiply by the square root of 2.
Multiplying square roots and whole numbers are fairly easy, just combine it like multiply with a variable. Since the rule for a 45-45-90 triangle is to multiply the side length by the square root of 2 to get the hypotenuse then you would multiply 17 by the square root of 2 which will give you answer choice C.
If you encounter a similar problem like this but with the hypotenuse to the side length then you would do the OPPOSITE of multiplying by the square root of 2 (which would be dividing the hypotenuse by the square root of 2).
Which expression is equivalent to 10√5
Answers
Answer:
A. √500
Step-by-step explanation:
Since 500 = 5·100 = 5·10² you can move the 10² out of the √ as 10.
Hence 10√5 = √500
So we're using these rules:
√a·b = √a·√b
and of course
√a² = a (a>0)

find the missing letter which is N.the length is 25 in and the perimeter is 86 in
Answers
Answer:
Step-by-step explanation:
length = 25 in
Perimeter = 86 in
2*(length + width) = 86
2*(25 + N) = 86
Divide both sides by 2
25 + N = 86/2
25 + N = 43
Subtract 25 from both sides
25 + N - 25 = 43 - 25
N = 18
