To prove triangles similar, we only need to prove corresponding angles congruent OR corresponding sides are proportional. However, with a quadrilateral we need to prove corresponding angles congruent AND corresponding sides are proportional. Explain in your own words why it takes more to prove that quadrilaterals are similar. Include examples demonstrating how “just angles” or “just sides” is not enough.
It takes more to prove that quadrilaterals are similar because there are several quadrilaterals such as rectangle, square, etc.
What is a quadrilateral?It should be noted that a quadrilateral simply means a shape that has four sides and four angles.

The answer is (x+4) (x-2) =x.x
Square (Rug A) has area x times x = x^2 (All sides of square are equal)
x is the side of Rug A
For the Rectangle (Rug B) it mentioned that it has a length of that is 4 ft greater than the length of Rug A. The expression could be written as Length = (x+4)
It also mentions that the width of Rectangle is 2 ft less than Rug A. The expression could be written as Width = (x-2)
So, if you multiply (x+4) and (x-2), will give you the area of rectangle (Rug B)
The question mentions that the area of the rectangle and square are equal, so therefore the answer is (x+4) (x-2) =x.x

Select the correct answer.
A system of equations and its solution are given below.
System A
x + y = 8
4x - 6y = 2
Solution: (5,3)
Choose the correct option that explains what steps were followed to obtain the system of equations below.
System B
x + y = 8
10x = 50
Answer:
B will be the answer...
Step-by-step explanation:
The second equation in system B is only in terms of y, so we need to use elimination to eliminate the x term from the second equation in system A.
To do that, we need to multiply the first equation by 5.
5 (-x − 2y = 7)
-5x − 10y = 35
Add to the second equation. Notice the x terms cancel out.
(-5x − 10y) + (5x − 6y) = 35 + (-3)
-16y = 32
Combining this new equation with the first equation from system A will get us system B.
-x − 2y = 7
-16y = 32
Answer:
To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 6. The solution to system B will be the same as the solution to system A.

boat traveled downstream a distance of 60 mi and then came right back. If the speed of the current was 6 mph and the total trip took 4 hours find the average speed of the boat relative to the water.
Answer:
7.5mph
Step-by-step explanation:
Let the average speed of the boat to be x mph.
Total Distance = Avg. Speed x Total Time
60 = ((x+6) + (x-6))(4)
60 = (x+6+x-6)(4)
(2x)(4)=60
2x=60/4
2x = 15
x = 15 /2
x = 7.5mph
Answer:
15 +√261 ≈ 31.155 mph
Step-by-step explanation:
The time for the trip can be found by dividing the distance by the speed.
__
setupThe relation between time, speed, and distance is ...
time = distance/speed
The speed for the downstream leg was the sum of the boat speed (b) and 6 mph. The speed for the upstream leg was the difference. So the total trip time was ...
4 = 60/(b +6) +60/(b -6) . . . total time is the sum of the times for the legs
__
solutionMultiplying by the product of the denominators, we have ...
4(b +6)(b -6) = 60(b -6) +60(b +6)
b² -36 = 30b . . . . divide by 4 and simplify
b² -30b = 36 . . . . put in a form useful for completing the square
(b -15)² = 36 +15² . . . . . complete the square
b -15 = √261 . . . . . . . . take the square root (negative root is extraneous)
b = 15 +√261 ≈ 31.155 . . . . add 15
The average speed of the boat was about 31.155 mph.

Let (-7,3) be a point of terminal side of 0
Find Cos Sec Cot
The trigonometry ratios are cos(θ) = -7/√58, sec(θ) = -√58/7 and cot(θ) = -7/3
How to determine the trigonometry ratios?The point on the terminal side is given as:
(x, y) = (-7, 3)
Start by calculating the hypotenuse using:
[tex]h= \sqrt{x^2 + y^2[/tex]
So, we have:
[tex]h= \sqrt{(-7)^2 + 3^2[/tex]
Evaluate
[tex]h= \sqrt{58[/tex]
The cosine is then calculated using:
cos(θ) = x/h
This gives
cos(θ) = -7/√58
The secant is then calculated using:
sec(θ) = 1/cos(θ)
This gives
sec(θ) = -√58/7
The cotangent is then calculated using:
cot(θ) = cos(θ)/sin(θ)
Where
sin(θ) = y/h
So, we have:
sin(θ) = 3/√58
So, we have:
cot(θ) = (-7/√58)/(3/√58)
This gives
cot(θ) = -7/3

125 = 5 × 5 × 5
150 = 2 × 3 × 5 × 5
225 = 3 × 3 × 5 × 5
Next, identify those prime factors that the 3 numbers have in common and multiply them.
the common factors are 5 × 5 = 25
