C²+5c-24=0 cant figure out how to solve this
frosja888 [35]
Just solve the quadratic, you need to figure out what value you can use to FOIL and get c^2+5c-24=0. so you need to figure out what values you can add together to get 5 and multiply together to get -24 so try (c+8)(c-3) here 8 and 3 make sense since 8-3 = 5 and 8*-3=-24 so the answer is (c+8)(c-3).

Adam lived a quarter of his life as a boy as fifth as a young man, a third in middle-age and 13 years in retirement. How old was
Anika [276]

ANSWER

Find out the how old was we when he died.

To proof

Let us assume that the age of the Adam be x

As given

Adam lived a quarter of his life as a boy as fifth as a young man, a third in middle-age and 13 years in retirement.

x =\frac{x}{4} +\frac{x}{5} +\frac{x}{3} + 13

L.C.M of denominator i.e ( 4,5,3) =60

than the equation becomes

60x = 15x + 12x +20x +780

60x - 47x = 780

13x = 780

x =\frac{780}{13}

x = 60 years

therefore the Adam age  when he died is 60 years.

Hence proved
