Given:
The vertices of a rectangle are (6, 3), (−6, 3), (−6, −1), and (6, −1).
To find:
The perimeter of the rectangle.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}[/tex]
Let the vertices of a rectangle are A(6, 3), B(−6, 3), C(−6, −1), and D(6, −1).
Using the distance formula, we get
[tex]AB=\sqrt{(-6-6)^2-(3-3)^2}[/tex]
[tex]AB=\sqrt{(-12)^2-(0)^2}[/tex]
[tex]AB=\sqrt{144}[/tex]
[tex]AB=12[/tex]
Similarly,
[tex]BC=\sqrt{\left(-6-\left(-6\right)\right)^2+\left(-1-3\right)^2}=4[/tex]
[tex]CD=\sqrt{\left(6-\left(-6\right)\right)^2+\left(-1-\left(-1\right)\right)^2}=12[/tex]
[tex]AD\sqrt{\left(6-6\right)^2+\left(-1-3\right)^2}=4[/tex]
Now, the perimeter of the rectangle is:
[tex]Perimeter=AB+BC+CD+AD[/tex]
[tex]Perimeter=12+4+12+4[/tex]
[tex]Perimeter=32[/tex]
Therefore, the perimeter of the rectangle is 32 units.
Can someone help me please
Answer:
A = 2x² + x - 45
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = length × breadth , thus
A = (2x - 9)(x + 5) ← expand using FOIL
= 2x² + 10x - 9x - 45 ← collect like terms
= 2x² + x - 45

Answer:
A
Step-by-step explanation:
49y² - x² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
49y² - x²
= (7y)² - x²
= (7y - x )(7y + x) → A

Answer:
Step-by-step explanation:
1.)12.
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator.
Thus, the answer to 4 divided by 1/3 in fraction form is:
[tex]\frac{12}{1}[/tex]
To make the answer to 4 divided by 1/3 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
12
The answer is rounded to the nearest two decimal points if necessary.
[tex]\frac{12}{1}[/tex] is an improper fraction and should be written as 12.
2.) 9

which equation can be used to solve x in the diagram??
a) 13x - 5x = 180
b) 5x + 13x = 90
c) 5x + 13x = 180
d) 5x = 13x
no links pls!!
Step-by-step explanation:
C) 5x + 13x = 180°
Because, the angles in the diagram add up to 180° because it's a straight angle
So, the sum of both of them will give 180
So option (C) is right

The Halloways are taking a trip to Maine. Mr. Halloway knows that it is about 885 miles to their destination in Maine from their home in Ohio. He knows the average speed along his route will be 65 miles per hour. How many hours is the drive?
Answer:
Number of hours= 13.61 hours
Step-by-step explanation:
Giving the following information:
Mr. Halloway knows that it is about 885 miles to their destination.
Average speed= 65 miles per hour
To calculate the number of hours to be drive, we need to use the following formula:
Number of hours= total miles / miles per hour
Number of hours= 885/65
Number of hours= 13.61 hours

Why would the velocity of a river affect its ability to erode sediment?
The power of a river to cause erosion and carry sediment depends on several factors. A rivers slope, volume of flow, and the shape of its stream bed all affect how fast the river flows and how much sediment it can erode. ... When a river slows down, it drops its sediment load.
The velocity of the river that impact the capability for eroding the sediment should be explained below.
Impact on the velocity of a river:In the case when the slope should be considered too gentle and here the velocity should be too slow for transporting the sediments that being supplied via weathering and erosion also the sediments should be piled up.
It rised the gradient that resulted the water to flow quickly that increased the erosion and transport due to which it decreased the gradient.
