360 - 90 = 270
Plug in the two expressions
270 = (7x + 6) + (6x - 7) -> expand
270 = 42x^2 - 1 -> bring the one to the other side and add
271 = 42x^2 -> divide by 42
6.4 = x^2 -> find the square root
2.5 = x
Then solve both equations with x = 2.5 :^)
Hope this helped!!
Answer:
1800
Step-by-step explanation:
30 x 60
we know that
To find the solution let's factor the equation
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
therefore
the answer is the option
A. –6 or x = 2

Answer:
Step-by-step explanation:
Remark
The formula for the circumference is C = 2*pi * r
Givens
r = 50 feet
pi = 3.14
Solution
C = 2* 3.14 * 50
C = 314 feet
So one turn of the ferris wheel would allow a person to travel 314 feet around the circle.
