Sure! So this is ready as "the cube root of 125". This basically means, "what number cubed can get me 125?"
Let's go through our options.
We can rule out D, as D cubed would be unreasonably big.
We can also rule out C, because 375 cubed is easily over 10000, you know this even if you haven't computed it all, just compute the 300 cubed.
We can rule out B, too. 41 squared is already over 125, therefore it can't be the answer.
Therefore our answer is A, 5. We can check that by cubing 5, and that indeed gets us 125.
Hope this helps!
Infinity, because there is no set amount of years the price can rise. The price and keep rising as long as he rents, and it's stated that he will not ever buy a house
If you're allowed to repeat letters, then it's 12x12x12x12x12. If not, then it's 12x11x10x9x8.
The formula to use is:
A=P(1+r/n)^nt
Plug in the values:
A=1400(1+.06/2)^2(10)
A=$2528.56 (rounded off)
Make sense?
W=2L-5
-------------
A=L*W
=L(2L-5)
=2L²-5L
-------------
dA/dL=4L-5
When dA/dL=0,
4L-5=0
4L=5
L=5/4
----------------
When L=5/4
A=5/4*(2*(5/4)-5)
=5/4*(10/4-20/4)
=5/4*((-10)/4)
=5/4*(-5/2)
=-25/8
--------------------------------
