Graph it to a then to b then to c and you will have your answer sikew
Stop 1 : -
15 + 5 = 20
20 - 2 = 18
So, on the first stop 18 passengers were left on the bus going to the next stop.
Stop 2 : -
18 + 3 = 21
21 - 15 = 6
So, 6 passengers get off at the 2nd stop.
Hope I helped ya!!
17.29 feet, using the Pythagorean theorem.
4 x^2 + 20 x + 25 = 7
Divide both sides by 4:
x^2 + 5 x + 25/4 = 7/4
Write the left-hand side as a square:
(x + 5/2)^2 = 7/4
Take the square root of both sides:
x + 5/2 = sqrt(7)/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
x = sqrt(7)/2 - 5/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
Answer: x = sqrt(7)/2 - 5/2 or x = -5/2 - sqrt(7)/2
For the first problem, the triangle is equilateral. This means that all three sides will have the same length. So you need to find a value for x that makes all three of those statements equivalent. I believe you could find it using a system of equations... but it’s been a while so don’t quote me on that.
For the second, ce and de are equal. Set them equal to each other and solve for x. Then plug that x value back into the side lengths.
