Answer:
Option 4 is correct.
Step-by-step explanation:
Given the following options
we have to choose the difference of cubes.
Option 1:
![9w^{33}-y^{12}](https://tex.z-dn.net/?f=9w%5E%7B33%7D-y%5E%7B12%7D)
![9(w^{11})^{3}-(y^4)^3](https://tex.z-dn.net/?f=9%28w%5E%7B11%7D%29%5E%7B3%7D-%28y%5E4%29%5E3)
which is not the difference of cubes
Option 2:
![18p^{15}-q^{21}](https://tex.z-dn.net/?f=18p%5E%7B15%7D-q%5E%7B21%7D)
![18(p^5)^3-(q^7)^3](https://tex.z-dn.net/?f=18%28p%5E5%29%5E3-%28q%5E7%29%5E3)
which is not the difference of cubes
Option 3:
![36a^{22}-b^{16}](https://tex.z-dn.net/?f=36a%5E%7B22%7D-b%5E%7B16%7D)
![(6a^{11})^2-(b^8)^2](https://tex.z-dn.net/?f=%286a%5E%7B11%7D%29%5E2-%28b%5E8%29%5E2)
which is the difference of square
Option 4:
![64c^{15}-a^{27}](https://tex.z-dn.net/?f=64c%5E%7B15%7D-a%5E%7B27%7D)
![(4c^5)^3-(a^9)^3](https://tex.z-dn.net/?f=%284c%5E5%29%5E3-%28a%5E9%29%5E3)
which is the difference of cubes.
The answer would be C, oxygen because there was not a sufficient amount.
<1 = 123
60 + 63 = 123
180 - 123 = 57
180 n- 57 = 123
Triangle angle-sum theorem
Alternate exterior angles theorem (?)
Same side interior angles theorem
idk what the last one is about sorry
hope this helps
5 divide by 30 equals 6.12 minus 6 equals 6 so she has to make at least 6 pies.
