Answer:
4
Step-by-step explanation:
subsitute the value of the variable into the expression and simplify.
B(5,1) I’m smart and don’t worry the answer is correct
Answer:
x = 150
Step-by-step explanation:
What we need to do is first use the sum of interior angles theorem to find the total sum of this odd hexagon.
n = sides of the shape.
(n-2)*180° = Sum of interior angles
For us this would be 720° total. Now make an equation
121 + 96 + 101 +162 + 90 + x = 720
Then we simplify
570 + x = 720
-570 -570
And then subtract 570 on both sides and we get our answer.
x = 150
We have been given Marley was asked to solve
using the Quadratic Formula. She found the discriminant first and decided she did not need to continue with the Quadratic Formula.
We are asked to determine whether Marley is correct or not.
We know when an equation is in form
, we can use discriminant to check for the real solutions of equation.

If
, then the equation will have two real solutions.
If
, then the equation will have one real solution.
If
, then the equation will have no real solutions.
Let us find discriminant.




Since
, therefore, the equation will have no real solutions, so Marley is correct.
