Answer:

136.3

Step-by-step explanation:

I assume it is asking you to add both 9.3x and 8.9y together. First you would multiply 9.3 by 7 and 8.9 by 8 which gives you 65.1 + 71.2 which equals 136.3.

help me please can someone please help i beg you. i have to say why this is wrong and solve this correctly. i beg you please
e-lub [12.9K]

Answer:

The person solving the problem first subtracted 6 from 15. Since the cube root is next to the six, the problem should be read as 15-6(\sqrt[3]{\frac{-1000}{27} } ) rather than (15-6)(\sqrt[3]{\frac{-1000}{27} } ).

  • To solve it correctly, first find the cube root of -1000/27: <u>-10/3</u>
  • Next, multiply by 6: -20
  • Finally, subtract from 15: 35

please lmk if anything is wrong with my answer, hope this helps :)
