F(1) = (1)^3 + 2(1)^2 - 5(1) - 6 = 1 + 2 - 5 - 6 = -8; x = 1 is not a solution to the polynomial.
f(-1) = (-1)^3 + 2(-1)^2 - 5(-1) - 6 = -1 + 2 + 5 - 6 = 0; x = -1 is a solution to polynomial.
From the options, a or c has x = -1, both has x = , so lets check for x = 3
f(3) = (3)^3 + 2(3)^2 - 5(3) - 6 = 27 + 18 - 15 - 6 = 24; x = 3 is not a solution to the polynomial.
Therefore the solutions to the polynomial are x = -3, x = -1, x = 2
Answer:
The two possible cases are
(i) the base angles are each 40° and the vertex angle is 100°,
(ii) the base angles are each 70° and the vertex angle is 40°.

❖ A number y increased by 5 is at least -21.
❖ First, if you come across the word "increased" it means we
"increase" a number, or add something to that number, like
y increased by 5 
Now, we are also given that this expression is at least -21, which means it can't be -21; it can be -21 or it can be greater than -21.
So we have
<em>Solving for y</em>
<em></em>
- Subtract 5 on both sides:-
So the values of y greater than or equal to -26 will make this inequality true.

Step-by-step explanation:
Answer to question 1:
divide what she owed by 4.
Since she owes a quarter or 1/4 of her money. So you would divide by four.
Answer to question 2:
-18
if you multiply -3 by 6 you would get -18.
