Answer:
B) 686 cubic units
Step-by-step explanation:
If one cube has a side length of 7, then it equals to 343 cubic units. Since there are 2 cubes, this translates to 686 cubic units.
The function rule for x is +1. When you want to get the next number in the set, you add one to the previous number. For example, -1 + 1 = 0.
The function rule for y is - 5. When you want to get the next number in the set, you subtract five to the previous number. For example, 9 - 5 = 4.
Hope this helps!
First distribute
a(b+c)=ab+ac so
2(x+3)=2x+6
-3(2-2x)=-6+6x
5x+3=2x+6-6+6x
add like terms
5x+3=2x+6x+6-6
5x+3=8x+0
subtract 5x from both sides
3=3x
divide both sides by 3
1=x
there are 1 solutions
You did not show the diagram that was made but from what I already know, I'm pretty sure that the answer is:
1.) Energy is used up.
2.) Both - Oxygen is used up, and Carbon dioxide is used up.
3.) Glucose is broken down
