Complementary angles
Step-by-step explanation:
Complementary angles are when two angles add up to 90 degrees.
3x + 10 + 47 = 90
3x + 10 = 43
3x = 33
x = 11
please hurry. Find the area of the rectangle. 7n^2 + 3n 2n^3
Area of a rectangle = Width * Length
In our problem,
width = 2n^3
length = 7n^2 + 3n
Area = 2n^3 (7n^2 + 3n)
Distribute the 2n^3
Area = 14n^5 + 6n^4
The required, area of the given rectangle is given as 14n⁵ + 6n⁴.
What is a rectangle?The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
What is the area of the rectangle?The area of a rectangle is the product of the length and width of the rectangle.
Here,
In the question, we are given,
length = 7n² + 3n
width = 2n³
Area of the rectangle = length × width
Area of the rectangle = 7n² + 3n × 2n³
Area of the rectangle = 14n⁵ + 6n⁴
The required, area of the given rectangle is given as 14n⁵ + 6n⁴.

Answer:
[tex]m=-2[/tex]
Step-by-step explanation:
[tex]3=m+5[/tex]
Switch sides:
[tex]m+5=3[/tex]
Subtract 5 from both sides:
[tex]m+5-5=3-5[/tex]
[tex]m=-2[/tex]
Answer:
-2
Step-by-step explanation:
1. Add the same term to both sides of the equation
3=m+5
( 3-5 = m + 5 -5)
2. Simplify
-subtract the numbers
- add the numbers
3. Solution
-2 = m

write an equation that represents the set of points that are 8 units from (-8,-7)
The equation that represents the set of points that are 8 units from (-8,-7) is [tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex] + 49 = 0.
What is the distance between two points ?
Distance between two points is the length of the line segment that connects the two locations in a plane.
We know that the distance between two points is calculated by using the distance formula which is given as :
D = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }[/tex]
Here ; let's assume the first point is (x1, y1). It is given that other point is (x2, y2) = (-8 , -7) and distance D = 8 units. Now use these data to find out the equation :
8 = [tex]\sqrt{(-8 - x_{1})^{2} + (-7- y_{1})^{2} }[/tex]
Squaring on both sides , we get :
64 = [tex](-8 - x_{1} ) ^{2}[/tex] + [tex](-7 - y_{1})^{2} }[/tex]
64 = 64 + [tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + 49 + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex]
[tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex] = 64 - 64 - 49
[tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex] = -49
or
[tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex] + 49 = 0
Therefore , the equation that represents the set of points that are 8 units from (-8,-7) is [tex]x_{1} ^{2}[/tex] + 16[tex]x_{1}[/tex] + [tex]y_{1} ^{2}[/tex] + 14[tex]y_{1}[/tex] + 49 = 0.

Step-by-step explanation:
Points A, B, and C are collinear and AB:AC=2:5. Point A is located at (-3,-4), point B is located at (m,n) and point C is located at (2,6). What are the values of m and n? Show all work.
Answer:
m = -11/7
n = -8/7
Step-by-step explanation:
Here, what we want to calculate is the coordinates of the point B
Let’s consider the straight line as A B C
we can see that actually, the point B divides the line into the ratio 2:5 since AB:AC is 2:5
Thus, by using the internal division formula (section formula) with the ratio of division, we can get the coordinates of point B
Mathematically, the formula for internal division is given as follows;
B = ( (mx2 + nx1) /m + n , (my2 + ny1)/( m + n))
From the question;
m:n = 2:5
Thus m = 2, n = 5
(x1,y1) are coordinates of A
x1 = -3 , y1 = -4
(x2, y2) are coordinates of C
x2 = 2 , y2 = 6
Thus, substituting these values into the equation we have;
B ={ 2(2) + 5(-3)}/(2+5) , {2(6) + 5(-4)}/(2+5)
B = (-11/7, -8/7)

1. if a = 16 and b= 12, find c
Answer:
20
Step-by-step explanation:
The pythagorean theorem states that
[tex]a^2+b^2=c^2[/tex]
So [tex]16^2 + 12^2 = c^2\\256+144 = c^2\\400 = c^2[/tex]
You would then do
[tex]400 = c^2\\\sqrt{400} = c[/tex]
Because a square root is the opposite of a square.
[tex]\sqrt{400} = 20[/tex]
because 20 * 20 = 400

Step-by-step explanation:
Given that,
√3/√6
The denominator is √6
We know that
The rationalising factor of √a is √a
Therefore, the rationalising factor of √6 is '√6’.
Now,
⇛(√3/6) × (√6/√6)
⇛{√3(√6)}/(√6)(√6)
⇛(√3*6)/(√6)²
⇛(√18)/(6)
⇛(√2*9)/6
⇛(2√2)/6
⇛√2/2
Hence, the denominator is rationalised.
