You have $200 in a savings account. Each week for 8 weeks, you take out $18 for spending money. How much money is in your account at the end of 8 weeks

$56

Step-by-step explanation:

Since you are doing this for 8 weeks, you multiply 8 by 18 and you get 144. You then subtract 144 from 200 and get 56 dollars.

Hope this helped!

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
