Solve the equation by graphing. if exact roots cannot be found, state the consecutive integers between which the roots are located x2 +6x +8= 0

x= -4 and x=-2

Step-by-step explanation:

Using a graphing calculator (See picture attached) we find that the solution to the equation are the x-values at which the graph of the function intercepts the x-axis. It ocurrs at x= -4 and x=-2.

Given that exact roots were found, there's no need to state the consecutive integers between which the roots are located.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
