The correct options are:
The ordered pair (5, −6) is a solution to the first equation because it makes the first equation true.
The ordered pair (5, −6) is not a solution to the system because it makes at least one of the equations false.
Step-by-step explanation:
Given equations are:

first of all we have to put the point in both equations to check if the point holds true on both equations
So,
Putting the point in the first equation

Putting the point in second equation

So,
The correct options are:
The ordered pair (5, −6) is a solution to the first equation because it makes the first equation true.
The ordered pair (5, −6) is not a solution to the system because it makes at least one of the equations false.

Answer:
-42
Step-by-step explanation:
A negative times a positive is a negative so

equals -42
Ok so the rectangle is 12x6 which is 72. The entire top part is 18 which means the other triangle side is 6. 6x6 = 36 so 72+36 is 108
Answer:
A
Step-by-step explanation:
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
