V=(4/3)r^3
first one
V=(4/3)(1/2)^3
V=4/24
V=1/6
V=(4/3)(3/4)^3
V=108/192
V=9/16
compare
1/6 to 9/16
16/96 compared to 54/96
well, the bigger ballon is 19/8 ft^3 bigger than smaller oe
Answer:
10 + (-14) = -4
Step-by-step explanation:
Given that,
Diamond used a number line to add. She started counting at 10, and then she counted until she was on the number −4 on the number line.
For addition, she will add 10 and (-14) as follows :
10 + (-14) = -4
So, the crrect option is (b) "10 + (-14) = -4".
Answer:
Hope this helps!

No, they are not parallel because they have different slopes.]
Answer:
2 (x + 3)^2 - 2
Step-by-step explanation:
1. Factor the 2 out of the equation (don't forget about it - it will be used later). This gives you x^2 + 6x + 7
2. Subtract the 7 over. This gives you x^2 + 6x = -7
3. Take b (6), divide it by 2 (3), and square it (9). Then add that to both sides of the equation. This gives you x^2 + 6x + 9 = 2
4. Factor the left side of the equation. This gives you (x + 3)^2 = 2
5. Subtract the 2 over. This gives you (x + 3)^2 - 2
6. Remember that 2 we factored out of the equation earlier? Well that goes in front of the parentheses now, giving you the final answer of 2 (x + 3)^2 -2
