The volume of the figure is since you have to do width times heigh so 25 times 8 which would be 200 as your answer.
Answer: Third option
Step-by-step explanation:
One of the ways of solving a system of equations is by equating the equations and solving for one of the variables.
In this case we have the system:
Note that if 
is equal 
and also equals 
Then logically must be equal to .
We write equality.
Then the correct answer is the third option.
We can also solve for the variable x
Answer:
-(x + 1)(7x - 12)
Step-by-step explanation:
Step 1: Factor out a -1
-1(7x² - 5x - 12)
Step 2:
Think. Answer this question: "What 2 numbers multiply up to -12 and adds up to -5 while 7 is an x coefficient?". You answer should be -12 and 1.
So, <em>factor</em>.
-1(x + 1)(7x - 12)
To double check, just expand/FOIL everything and see if it is the same as the original expression.
