It takes 8 people to pull a 16 ton truck. How many people would it take take to pull a 60 ton truck? I got 30 people am I right?
kiruha [24]
8 people pull a 16 ton truck
we can make that a proportion
8:16 
which can be reduced to 
1:2 

that means 1 person can pull 2 tons

to pull a 60 ton truck, you would have a proportion of
x: 60 = 1:2

cross multiply and you get

60 = 2x
x = 30

yes, you're right!

Solve for x in the equation x2 + 14x+17--96
Veseljchak [2.6K]

Answer:

Option B.

Step-by-step explanation:

If a quadratic equation is defined as ax^2+bx+c=0, the by quadratic formula

x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}

Consider the given equation is

x^2+14x+17=-96

We need to find the value of x.

Add 96 on both sides.

x^2+14x+17+96=-96+96

x^2+14x+113=0

Here, a=1, b=14 and c=113. Using quadratic formula we get

x=\dfrac{-14\pm \sqrt{14^2-4(1)(113)}}{2(1)}

x=\dfrac{-14\pm \sqrt{-256}}{2(1)}

x=\dfrac{-14\pm \sqrt{256}\sqrt{-1}}{2}           (\sqrt{-1}=i)

x=\dfrac{-14\pm 16i}{2}

x=-7\pm 8i

The value of x are x=-7 + 8i and x=-7 - 8i.

Therefore, the correct option is B.
