Is that supposed to be x² -4x -5 = 0 or x²-4-5=0 as written? We'll do both.

As written it's

x²=9 so x=±3, no quadratic formula required.

Let's assume you meant

x² -4x - 5 = 0

So much temptation. This factors as

(x-5)(x+1)=0 so roots x=5, x=-1. But that didn't use the quadratic formula..

There's a shortcut to the quadratic formula called the Shakespeare Quadratic Formula (2b or -2b) that's useful when the linear term is even.

In that case x²-2bx+c has zeros at z=b±√(b²-c)

x = 2 ± √(4 - -5) = 2 ± √9 = 2 ± 3 = { -1 , 5 }

OK, let's do it like they want

x² - 4x - 5 = 0

We have a=1, b=-4, c=-5 and the quadratic formula

Answer: **x=-1 or x=5**

Answer: X is equal to 55.

Step-by-step explanation:

You can determine that the triangle is an isosceles triangle because of its side lengths.

Therefore you know that value of the angle it's not asking for is also x. Since a triangle's angles always measures 180. You can say that 180 = 70 + 2x.

You can now solve for x.

180 = 70 + 2x

-70 -70

110 = 2x

55 = x

** A) ****she will not have moved relative to the Earth**

(she will have moved 0 m relative to the bus, because Cheryl's speed and bus speed are the same. Cheryl will always keep the distance of 10 m between her and the bus)
