Answer:
x = 5
Step-by-step explanation:
2⁴(2x) = 2⁵(x + 3)
2^8× = 2^5x + 15
cancel out the 2
8x = 5x + 15
8x - 5x = 15
3x = 15
divide through by 3
x = 5

Step-by-step explanation:
the sun shines on a flagpole, causing a shadow to be cast on the ground. the distance from the base of the pole to the tip of the shadow is 49 feet. at that time of day, the sun's rays make an angle of 38° with the ground. How tall is the flagpole?
Answer:
30.17feet high
Step-by-step explanation:
Given the following
the distance from the base of the pole to the tip of the shadow = 49feet (hypotenuse)
angle of elevation = 38°
Required
Height of the flagpole (opposite)
Using the SOH CAH TOA identity
Sin theta = opposite/hypotenuse
Sin 38 = H/49
H = 49sin38
H = 49(0.6157)
H = 30.17feet
Hence the flagpole is 30.17feet high

b) 43 degrees
Step-by-step explanation:
Answer:
Choice B
Step-by-step explanation:
The bottom right angle is 80° since thats the value of its complement
Subtract 180-123 to get the complement of the bottom left and the value of the bottom left, 57°
Since all the interior angles in a triangle will add up to 180° add 57 and 80 to get 137 then subtract 137 to get the value of x, 43.

Las longitudes de dos lados de un octágono regular están representadas por las expresiones 2x + 4 y 3x-8. Encuentra la longitud de un lado del octágono
Answer:
La longitud del lado del octágono es de 28 unidades.
Step-by-step explanation:
Si las longitudes de los dos lados pertenecen a un octágono regular, entonces se satisface la siguiente condición:
[tex]2\cdot x + 4 = 3\cdot x - 8[/tex] (1)
A continuación, despejamos [tex]x[/tex] en (1):
[tex]3\cdot x - 2\cdot x = 4 + 8[/tex]
[tex]x = 12[/tex]
Ahora, determinamos la longitud del lado del octágono: ([tex]x = 12[/tex])
[tex]l = 2\cdot x + 4[/tex]
[tex]l = 28[/tex]
La longitud del lado del octágono es de 28 unidades.

Answer:
m<CAO = 56
Step-by-step explanation:
When two parallel lines are intersected by a transversal, the same-side interior angles are supplementary, meaning that their angle measures add up to (180) degrees. Using this information, substitute in the given values and solve for the unknown,
(m<DOA) + (m<CAO) = 180
Substitute,
3x + 40 + 2x = 180
Simplify,
5x + 40 = 180
Inverse operations,
5x + 40 = 180
-40 -40
5x = 140
/5 /5
x = 28
Now substitute the value of (x) back into the given expression for the value of (<CAO). Solve to find the numerical value.
<CAO = (2x)
= 2(28)
= 56
Find the perimeter of a rectangle with length (x-5) and width (3x+1).
Answer:
8x-8
Step-by-step explanation:
P=s+s+s+s or in this case P= 2l+2w
P= 2(x-5)+2(3x+1)
P=(2x-10)+(6x+2)
P=8x-8
8x-8 will be the perimeter of a rectangle with length (x-5) and width (3x+1).
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Perimeter of rectangle = 2( length + width).
Given that,
Length of rectangle = x - 5
Width of rectangle = 3x + 1
Now,
Perimeter of rectangle = 2(width + length)
Perimeter of rectangle = 2(3x + 1 + x - 5)
The perimeter of the rectangle = 8x - 8
Hence "8x-8 will be the perimeter of a rectangle with length (x-5) and width (3x+1)".

You have a box with 5 blue marbles, 4 red marbles, and 9 yellow marbles. You are going to pull out one marble, record its color, put it back in the box and draw another marble. What is the probability of pulling out a blue marble followed by a yellow marble?
Answer:
I think it's 45/196.
Step-by-step explanation:
Not sure though, no explanation.
The probability of pulling out a blue marble followed by a yellow marble 25% or 0.25 .
What is probability ?
Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
Based on the given conditions, formulate 9 ×9÷((9 + 5 + 4) ×(9 +5 +4))
Calculate the product or quotient = [tex]\frac{81}{(9 +5 + 4) * (9 + 5 + 4)}[/tex]
Calculate the sum or difference= [tex]\frac{81}{(14 + 4) * (9 +5+4)}[/tex]
Calculate the sum or difference = [tex]\frac{81}{18 * (9+5+4)}[/tex]
= [tex]\frac{81}{18 * (14 + 4)}[/tex]
=[tex]\frac{81}{18 * 18}[/tex]
Calculate the product or quotient = [tex]\frac{81}{324}[/tex]
Cross out the common factor = [tex]\frac{1}{4}[/tex]
get the result 25% or 0.25
Therefore, The probability of pulling out a blue marble followed by a yellow marble 25% or 0.25 .

What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
y = 5x - 1
For x = -1,
y = -5 - 1 = -6
For x = 0,
y = - 1
For x = 1,
y = 5 - 1 = 4
For x = 2,
y = 10 - 1 = 9
