Penelope is 4 times old as jose. jose is 3 years older than eliot. if the sum of the ages of all three is 57, how old is jose?

10

Step-by-step explanation:

jose is x,so the penelope is 4x, eliot is x-3,

so :

x+4x+x-3=57,

then:

6x=60, x=10

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
