For this case we must solve the following equation:
We subtract 4 on both sides of the equation:
We square both sides of the equation:
We have an equation of the form:
Where:
The solutions are given by:
Substituting:
So, the roots are:
ANswer:
Answer:
Step-by-step explanation:
The given expression is
We group the constant terms on the right hand side to obtain;
We square both sides of the equation to remove the square root.
This will simplify to;
Answer:It’s B
maybe 11.2-9.6n...sorry if I get it wrong

The y-intercept is 15 and the slope is 30
How?
slope = change in y/change in x
1) Either or ∦ (only two possibilities)
2) Assume (one of two possibilities)
3) (if two parallel lines are cut by a transversal, the corresponding angles are congruent)
4) But is not congruent to (given)
5) So ∦ (only other possibility)
