x^2-4x-12
x -6
x +4
(x-6)(x+4)
Answer:
D) 3x^2 - 12
Step-by-step explanation:
Using PEMDAS;
There is no need to evaluate the part of the equation (x^2 - 8) because is no need to, as it is already in its simplest form.
We must evaluate the part of the equation continuing with, "- (-2x^2+4)," as it is not in its simplest form.
Evaluating "- (-2x^2+4)":
Step 1: Distributing the negative
Once distributing the negative symbol amongst the values within the parenthesis according to PEMDAS, we get "2x^2 - 4" as the product.
Step 2: Consider the rest of the equation to evaluate
Since the part of the equation is still in play here as it is a part of the original equation to be solved, we must evaluate it as a whole to get the final answer.
Thus,
x^2 -8 + 2x^2 - 4 = ___
*we can remove the parenthesis as it has no purpose, since it makes no difference.
Evaluating for the answer, we get,
x^2+2x^2 + (-8 - 4) = 3x^2 - 12
Hence, the answer is D) 3x^2 - 12.
Answer:
The answer to your question is A = 441.50 km²
Step-by-step explanation:
Data
Big triangle Small triangle
base = 33 km base = 19 km
height = 40 km height = 23 km
Process
1.- Calculate the area of the big triangle
Area = base x height / 2
Substitution
Area = 33 x 40 / 2
= 1320 / 2
= 660 km²
2.- Calculate the area of the small triangle
Area = 19 x 23 / 2
= 437 / 2
= 218.5 km²
3.- Subtract the small area to the big area
Share area = 660 - 218.5
= 441.50 km²
