12x*2y*3 - 2x -6x*3y*2 + 3y
Step-by-step explanation:
thats right if the * means to the power lol
1,000 times great. 50,000/50 = 1000
1.
![5\frac{3}{8}= \frac{43}{8}](https://tex.z-dn.net/?f=5%5Cfrac%7B3%7D%7B8%7D%3D%20%5Cfrac%7B43%7D%7B8%7D)
1c = 8 fl oz
![\frac{43}{8}= \frac{43}{8}\times8=43](https://tex.z-dn.net/?f=%5Cfrac%7B43%7D%7B8%7D%3D%20%5Cfrac%7B43%7D%7B8%7D%5Ctimes8%3D43)
Hence, a: 43 fl oz is correct
2.
1 inch = 0.0833 foot
43 inch = ![43\times0.0833=3.581](https://tex.z-dn.net/?f=43%5Ctimes0.0833%3D3.581)
Hence, option D
is correct.
3.
Length of material Mili has = ![7\frac{1}{2}= \frac{15}{2}](https://tex.z-dn.net/?f=7%5Cfrac%7B1%7D%7B2%7D%3D%20%5Cfrac%7B15%7D%7B2%7D)
Length needed for her skirt = ![4\frac{5}{8}= \frac{37}{8}](https://tex.z-dn.net/?f=4%5Cfrac%7B5%7D%7B8%7D%3D%20%5Cfrac%7B37%7D%7B8%7D)
Material left will be = ![\frac{15}{2}- \frac{37}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B2%7D-%20%5Cfrac%7B37%7D%7B8%7D)
=![\frac{60-37}{8}=\frac{23}{8}=2\frac{7}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B60-37%7D%7B8%7D%3D%5Cfrac%7B23%7D%7B8%7D%3D2%5Cfrac%7B7%7D%7B8%7D)
Hence, option A is correct.
Answer:
your final answer is 7.00
Answer:
2 - 16i
Step-by-step explanation:
![(1 + 5i) \times ( - 3 - i) \\ = 1 \times ( - 3 - i) + 5i \times ( - 3 - i) \\ = - 3 - i - 15i - 5 {i}^{2} \\ = - 3 - 16i - 5( - 1)..( \because \: {i}^{2} = - 1) \\ - 3 - 16i + 5 \\ = 5 - 3 - 16i \\ = 2 - 16i \\ \purple{ \boxed{ \bold{ \therefore \: (1 + 5i) \times ( - 3 - i) = 2 - 16i }}} \\](https://tex.z-dn.net/?f=%281%20%2B%205i%29%20%5Ctimes%20%28%20-%203%20-%20i%29%20%5C%5C%20%20%3D%201%20%5Ctimes%20%28%20-%203%20-%20i%29%20%20%2B%205i%20%5Ctimes%20%28%20-%203%20-%20i%29%20%20%5C%5C%20%20%3D%20%20-%203%20-%20i%20-%2015i%20-%205%20%7Bi%7D%5E%7B2%7D%20%20%5C%5C%20%20%3D%20%20-%203%20-%2016i%20-%205%28%20-%201%29..%28%20%5Cbecause%20%5C%3A%20%20%7Bi%7D%5E%7B2%7D%20%20%3D%20%20-%201%29%20%5C%5C%20%20-%203%20-%2016i%20%2B%205%20%5C%5C%20%20%3D%205%20-%203%20-%2016i%20%5C%5C%20%20%3D%202%20-%2016i%20%5C%5C%20%20%5Cpurple%7B%20%5Cboxed%7B%20%5Cbold%7B%20%5Ctherefore%20%5C%3A%20%281%20%2B%205i%29%20%5Ctimes%20%28%20-%203%20-%20i%29%20%3D%202%20-%2016i%20%7D%7D%7D%20%5C%5C%20)
