Answer: m = 15w
Step-by-step explanation: The reason why the answer is m = 15w is because since he said "He decides to increase the number of facts they are expected to memorize each week." Which makes it so that only the multiplication fact increased to 15 since they wouldn't put it lower then that. And there is a 2nd reason why the multiplication fact is 15. the reason why is because theres only one answer with 30 and its completely wrong. So therefore,, The answer is Multiplication Fact = 15weeks.
Answer: ∛(49) / 7Explanation:1) Given expression:
![\frac{ \sqrt[3]{7} }{ \sqrt[3]{49} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Csqrt%5B3%5D%7B7%7D%20%7D%7B%20%5Csqrt%5B3%5D%7B49%7D%20%7D%20)
2) Notice that 49 = 7².
3) With that in mind, rationalize by multiplying numerator and denominator by ∛7:
![\frac{ \sqrt[3]{7} }{ \sqrt[3]{49} } \frac{ \sqrt[3]{7} }{ \sqrt[3]{7} } = \frac{ \sqrt[]{7^2} }{ \sqrt[3]{7^3} } = \frac{ \sqrt[3]{49} }{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Csqrt%5B3%5D%7B7%7D%20%7D%7B%20%5Csqrt%5B3%5D%7B49%7D%20%7D%20%20%5Cfrac%7B%20%5Csqrt%5B3%5D%7B7%7D%20%7D%7B%20%5Csqrt%5B3%5D%7B7%7D%20%7D%20%3D%20%5Cfrac%7B%20%5Csqrt%5B%5D%7B7%5E2%7D%20%7D%7B%20%5Csqrt%5B3%5D%7B7%5E3%7D%20%7D%20%3D%20%5Cfrac%7B%20%5Csqrt%5B3%5D%7B49%7D%20%7D%7B7%7D%20)
Answer:
Look at the explanation
Step-by-step explanation:
after the second line (4x-2x) +20= 2
--------------
after the 3rd line
2x=2-20=-18
-------------------
after 4th line x=-18/2
-----------------------------------------------------------------------------
At the end
4(-9+5)=2(-9)+2
-36+20=-18+2
-16=-16 so it is right
