Answer:
The whole rectangle is in the 1st dimensions.
For how to do this, you need draw it in a grid chart.
SF = 9/18 = 1/2 or 0.5
answer
1/2 or 0.5
x= -15/4 => x= -3 3/4 or x= -3.75
Wrong because you need to add the -2 to the 8.... I hope this helps
The given expression is

We have to find the discriminant first . And for that, first we need to move whole terms of the left side to right side, that is


The formula of discriminant is

Substituting the values of a,b and c, we will get

And since the discriminant is greater than 0, or it is positive so we have two real roots.
Therefore the correct option is B .
