Answer:
A negative value or minus sign (-).
Step-by-step explanation:
A grouping symbol can be defined as a set of symbol used for organizing multiple numbers or variables in an algebraic equation.
In Mathematics, there are basically three (3) main grouping symbols and these are;
1. Parentheses ( ).
2. Braces { }.
3. Brackets [ ].
Additionally, grouping symbols are used to determine the order of operation when solving an algebraic equation.
Hence, when distributing a negative sign in front of grouping symbols, you must multiply each term inside the grouping symbols by a negative value or minus sign.
For example, given the algebraic equation X = 20 - 2(-1 + 2 - 5)
We would simplify the numbers in the parentheses (grouping symbol) by multiplying with -2;
X = 20 + 2 - 2 - 10
X = 20 - 10
X = 10
<em><u>Example 2;</u></em>
-(-1 - 2 + 3 - 4)
We multiply each term inside the grouping symbol by the minus sign
1 + 2 - 3 + 4 = 4.
1. 20
2. 20
3. 50
4. 40
5. 80
6. 70
7. 200
8. 400
9. 400
10. 400
11. 700
12. 500
When it says round to the nearest ten, it means in the ten times table, not the five times table. The same rule applies for the rounding to nearest hundred.

Answer:
The answer to your question is: letter C
Step-by-step explanation:
Data
Find the Parabola's equation and express the equation as an inequality.
Vertex = (0, -5)
Equation
(x- h) ² = 4p(y - k)
x² = y + 5
y = x² - 5
But, we need the area upper the parabola, then
y ≥ x² - 5
