Thomas tem uma receita para fazer bolos de arroz Krispie. A receita usa 120g de chocolate e 80g de Rice Krispies para fazer 12 bolos. (a) Quanto chocolate Thomas deve usar para fazer 30 bolos?

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

y - 25 = 2 ( x - 10 ) should be the answer

the answer on e2020 was d.

josh is incorrect

x= 7 and x= -1

step 2 is wrong and honestly first step is not needed, you just need to figure out the factors

i know its wrong because if you plug in the solutions josh found, they do not work (in the original equation)

x^2 -6x -7 = 0

(x-7) (x+1) = 0

x-7=0 x+1=0

x= 7 x= -1
