Mala is y years old her sister is 4 years older than mala write an expression in simplest form that repersents the sum of the ages of the sisters

We are given

Mala is y years old

So, Mala =y

her sister is 4 years older than Mala

So, Sister =y+4

now, we can find sum

Sum = Mala +Sister

Sum = y +y+4

Sum = 2y+4Answer

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
