Answer:
<h2><u><em>
x = 2 or -3</em></u></h2>
Step-by-step explanation:
What is x in x^2-x-6=0 pls
x^2 - x - 6 = 0
x + 2 * x - 3 = 0
x + 2 = 0
x - 3 = 0
x = 2 or -3
You plug in the given value for x.
F(-4)=(-4)2-4
F(-4)=-8-4
F(-4)=-12
F(0)=(0)2-4
F(0)=0-4
F(0)=-4
F(3)=(3)2-4
F(3)=6-4
F(3)=2
Answer:
Round to the nearest tenth. The diagram is not drawn to scale. Solution: We know that. cosθ = adjacent/hypotenuse. Substituting the values. cos22 = x/11.

Solution:
we are given that
John is 3 years older than Jim. Jim is 4 years less than half of Dana’s age.
Let the age of Jim be x years then we can say
Age of John
If diana Age is D then

It can be re-wriiten as
Diana age 
Given that their ages add up to 167

Hence jim is 39 nyears old, John is 39+3=42 years old. and Diana is 2*39+8=78+8=86 years old.
