Answer:
x=14
Step-by-step explanation:
3x+1 and 43 are both vertical angles so they are equivant.
3x+1=43
3x=42
x=14
The angles pictured are vertical angles so we set them equal to each other and solve for x.
3x + 1 = 43
3x = 42
x = 14
the answer is option #3… 14

(-14+3i)-(14i) = ?
Express your answer in the form
(a + bi).
Answers
Answer:
-14 - 11i
Step-by-step explanation:
You may be learning about the imaginary number, i. Even though i is actually the squareroot of -1, when you are doing algebra with it, it acts just like a variable does. The special thing to remember about i is that i^2 is -1. But we don't even need that right now for this problem.
(-14 + 3i) - (14i)
= -14 + 3i - 14i
Combine the i's
= -14 - 11i
That's it. The -14 is the a, and the -11 is the b in a+bi.
If necessary to fill in a computer answer that is already formatted with a plus, like:
_ + _i
then use -14 for a and -11 for b.

Answer:
4.Step-by-step explanation:
1:
Solve 4(1) + 2 = 18:
4(1) + 2 = 18= 4 + 2 = 18= 6 ≠ 18.1 is false.
2:
Solve 4(2) + 2 = 18
4(2) + 2 = 18= 8 + 2 = 18= 10 ≠ 182 is false.
3:
Solve 4(3) + 2 = 18
4(3) + 2 = 18= 12 + 2 = 18= 14 ≠ 183 is false.

Answer:
3060 [tex]cm^{2}[/tex]
Step-by-step explanation:
Find the cross-sectional area first of the trapezium
[tex]\frac{1}{2} (a+b)h[/tex]
So, [tex]\frac{1}{2}(6+34)15[/tex]
which is 40 / 2 x 15 = 20 x 15 = 300 [tex]cm^{2}[/tex]
Since there are 2 trapeziums (on the front and back): 300 x 2 = 600[tex]cm^{2}[/tex]
Find the Area of the Rectangles
The first rectangle on the top would be: 6x30 = 180 [tex]cm^{2}[/tex]
The slanted rectangle on the right would be: 25x30 = 750 [tex]cm^{2}[/tex]
The rectangle on the bottom would be: 30x34 = 1020 [tex]cm^{2}[/tex]
The hidden rectangle on the left would be: 17 x 30 = 510 [tex]cm^{2}[/tex]
So by combining all these calculations, you will get the total surface area which is:
600 + 180 + 750 + 1020 + 510 = 780 + 1770 + 510 = 2550 + 510 = 3060 [tex]cm^{2}[/tex]
solve the quadratic equation by taking the square root of (x+5)^2=16
Answers
(x-5)2=16
The first step you can take to solve this quadratic is to take the square root of both sides of the equation.
√[(x-5)2]=√(16)
When you take the square root of a term that is square it equals what is inside the parentheses.
So on the left side, you have x-5
On the right side, you are what we call "forcing" the square root. When this happens, you need to put ±. Why? Good question. When you square a negative number it positive; when you square a positive number it is also positive.
The √16 = ±4
So now we have;
x-5=±4
What do you do with that?
You make two separate equations.
x-5=4 and x-5=-4
x=9 x=1
Let's check our answers
x=9
(x-5)2=16
(9-5)2=16
42=16
16=16 it checks
x=1
(x-5)2=16
(1-5)2=16
(-4)2=16
16=16 it also checks
ANSWER: x=9 and x=1
[tex]~~~~~(x+5)^2 = 16\\\\\implies x+5 = \pm\sqrt{16}\\\\\implies x+5 = \pm 4\\\\\implies x =-5 \pm 4\\ \\\implies x = -9~~ \text{or}~~~x=-1[/tex]

Answer:

Isolate the term of x from one side of the equation.
-7x+21>-14First, subtract by 21 from both sides.
-7x+21-21>-14-21
Solve.
Add or subtract the numbers from left to right.
-14-21=-35
Rewrite the problem down.
-7x>-35
Then, multiply by -1 from both sides.
[tex]\sf{\left(-7x\right)\left(-1\right) < \left(-35\right)\left(-1\right)}[/tex]
Solve.
7x<35
Divide by 7 from both sides.
7x/7<35/7
Solve.
Divide the numbers from left to right.
35/7=5
x<5
Therefore, the correct answer is x<5.

The identity (x2 + y2) = (x2 -y2) + (2xy)? can be used to generate Pythagorean triples. What
Pythagorean triple could be generated using x = 8 and y = 3?
PLSSSS HELP
Answers
Answer:
48, 55, 73
Step-by-step explanation:
A Pythagorean triple are integers that can be entered in the Pythagorean theorem and be true
A common example is 3, 4, 5 because
[tex]3^{2} +4^{2} =5^{2}[/tex]
So here, you want to plug in the 8 for the x in the equation and 3 for the y
Then, what you are looking for is when the equation looks like
[tex]a^{2} + b^{2} = c^{2}[/tex]
So:
[tex](8^{2}+3^{2})^{2} = (8^{2} - 3^{2})^{2} + (2(8)(3))^{2}[/tex]
Simplify:
[tex]73^{2} = 55^{2} + 48^{2}[/tex]
We can see that the numbers in here follow the pythagorean theorem, where c = 73, b = 55, and a = 48
So the triple is 48, 55, and 73

Answers
The distance d from port c to port a from the given ship movement is gotten as; 7.7 miles.
How to calculate bearing distance?We are given;
Ferry travels east 3.5 miles from Port b.
Then it turns 75° south and travels for 6 miles till it gets to Port c
To get the distance d from port c to port a, we would make use of cosine rule which is;
c = √(a² + b² - 2ab*cos C)
Thus;
d = √(3.5² + 6² - 2(3.5 * 6)*cos 75))
d = 7.7 miles

Answers
Answer:
[tex]\dfrac{12x^{16}-18x^8-42x^6}{-6x^5}=-2x^{11}+3x^3+7x[/tex]
Step-by-step explanation:
Replace the questions marks with letters:
[tex]\dfrac{12x^{a}-18x^8+bx^6}{cx^d}=ex^{11}+3x^f+7x[/tex]
[tex]\textsf{Apply the fraction rule}\quad \dfrac{a+b+c}{d}=\dfrac{a}{d}+\dfrac{b}{d}+\dfrac{c}{d}[/tex]
[tex]\implies \dfrac{12x^{a}}{cx^d}-\dfrac{18x^8}{cx^d}+\dfrac{bx^6}{cx^d}=ex^{11}+3x^f+7x[/tex]
Taking the second term and calculating the coefficient of the denominator:
[tex]\implies -\dfrac{18x^8}{cx^d}=3x^f[/tex]
[tex]\implies \dfrac{-18}{c}=3[/tex]
[tex]\implies c=\dfrac{-18}{3}=-6[/tex]
Taking the first term, substituting the found coefficient of the denominator and calculating the coefficient e:
[tex]\implies \dfrac{12x^{a}}{cx^d}=\dfrac{12x^{a}}{-6x^d}=ex^{11}[/tex]
[tex]\implies e=\dfrac{12}{-6}=-2[/tex]
Taking the third term, substituting the found coefficient of the denominator, and calculating the coefficient of the numerator and the exponent:
[tex]\implies \dfrac{bx^6}{cx^d}=\dfrac{bx^6}{-6x^d}=7x[/tex]
[tex]\implies 6-d=1\implies d=5[/tex]
[tex]\implies \dfrac{b}{-6}=7 \implies b=-42[/tex]
Taking the first term, substituting the found coefficient and exponent of the denominator and the found coefficient e, and calculating the exponent of the numerator::
[tex]\implies \dfrac{12x^{a}}{cx^d}=ex^{11}[/tex]
[tex]\implies \dfrac{12x^{a}}{-6x^5}=-2x^{11}[/tex]
[tex]\implies a-5=11 \implies a=16[/tex]
Taking the second term, substituting the found coefficient and exponent of the denominator, and calculating the exponent f:
[tex]\implies -\dfrac{18x^8}{cx^d}=-\dfrac{18x^8}{-6x^5}=3x^f[/tex]
[tex]\implies f=8-5=3[/tex]
Substituting all found letters:
[tex]\dfrac{12x^{16}-18x^8-42x^6}{-6x^5}=-2x^{11}+3x^3+7x[/tex]

if a table shows the side length of a triangle and side 1 is 2(a+3) and side 2 is 3a-1 and the perimeter of the triangle is 6a-3. what is side 3
Answers
Answer:
Side 3 = a - 2
Step-by-step explanation:
Perimeter of a ∆ = sum of all the sides of a triangle
Perimeter of the given ∆ = 6a + 3 units
Side 1 = 2(a + 3)
Side 2 = 3a - 1
Side 3 = ?
Therefore:
Side 3 = Perimeter - sum of side 1 and 2
Thus:
Side 3 = 6a + 3 - [2(a + 3) + (3a - 1)]
Side 3 = 6a + 3 - [2a + 6 + 3a - 1]
Side 3 = 6a + 3 - [5a + 5]
Side 3 = 6a + 3 - 5a - 5
Side 3 = a - 2
