Answer:
1.1 : C - x^2 + x - 2
1.2 : A - 4a^2 - 6b^2 + 12
Step-by-step explanation:
When we have the expression p(x) - q(x), we can substitute those functions in:
(x^2 + 2x - 5) - (x - 3)
We can distribute:
x^2 + 2x - 5 - x + 3
and then combine like terms(2x & -x, -5 & 3)
x^2 + x - 2
This is the same as C.
We can start by distributing:
a^2 - 2b^2 + 3 - 4b^2 + 5 + 3a^2 + 4
Now, we can combine all the a^2 terms(a^2 & 3a^2):
4a^2 - 2b^2 + 3 - 4b^2 + 5 + 4
Then, we can combine the b^2 terms(-2b^2 & -4b^2):
4a^2 - 6b^2 + 3 + 4 + 5
and lastly, all the constants:
4a^2 - 6b^2 + 12
This aligns with option A

Answer:
Option C is correct.
Step-by-step explanation:
Distance already traveled by Ed miles
Also, Ed is driving at a rate of 63 miles per hour.
Distance Speed × Time
Distance traveled by Ed in hours
Total distance traveled by Ed
Also, total distance traveled by Ed is miles.
Therefore,
Option C is correct.
Answer:
x = 9
Step-by-step explanation:
Isolate the variable. Note the equal sign, what you do to one side, you do to the other. Multiply 3 to both sides.
(x/3)(3) = 3(3)
x = 3(3)
x = 3 * 3
x = 9
x = 9 is your answer.
