Y = 4x - 1
// Plug this in for variable y in equation [1]
[1] 20x - 5•(4x-1) = 5
[1] 0 = 0 => Infinitely many solutions
Answer:
No
Step-by-step explanation:
By using the Pythagoras theorem, it can be easily determined that whether the triangle is right triangle or not.
Thus, 
where where a and b are the legs and c is the hypotenuse.
Let a=6ft, b=21ft and c=23ft, then
which is not possible, therefore the given triangle is not right triangle because it does not satisfy the Pythagoras theorem.
(2a+2)(4a+4)
8a^2+8a+8a+8
The answer is 8a^2+16a+8
Answer:
48 Miles
Step-by-step explanation:
I assume you are asking for the distance in miles between the two cities.
1 Inch = 8 Miles,
Then 6 Inches = 8 Miles * 6
If the cities are 6 inches apart, the actual distance is 48 miles.
Just plug in the answers into the equation until it equals eachother;
3(6)+-3=15 15=15
2(6)+-3=6 6=6
Hope this helped!
