Answer:
3
Step-by-step explanation:
Subbing -3 for x in -x^2 - 4x, we get -(-3)^2 - 4(-3)
OR -9 +12
Final result: 3

Answer:
I think it's 832 units squared
Step-by-step explanation:
I used the formula for the surface area of a rectangular prism but just doubled the dimensions before plugging them in
None of the answers are correct
(x+3)^2 + 10 first you factor out the (x+3)
(x+3)(x+3) + 10
x^2 + 6x + 9 +10 simplify
x^2 + 6x + 19
The reaction is:
A ( g ) + 1/2 B ( g ) → C ( g )
We will rewrite it so the coefficient in the front of C is 1:
1/2 A + 1/4 B → C
So the rate of increasing of C is 4 times faster than the decrease of B.
The rate of B:
- 1.5 · 10^(-2) M/s : 4 = - 0.375 · 10^(-2) M/s = - 3.75 · 10 ^(-3) M/s
Answer: - 3.75 ·10^(-3) M/s
