Ice at 0C is added to 200g of water initially at 70C in a vacuum flask. when 50g of ice has been added and has a melted the temperature of the flask and contents is 40C. When a further 80g of ice is has been added and has all melted. the temperature of the whole becomes 10C. calculate the specific latent heat of fusion.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

jk it's 20

step-by-step explanation:

you divide them and then you get the answer i took this class this year

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
