Donna went to write spot and purchased $12.57 worth of snacks she has $ 12.10 on her debit card. What’s her new balance?

She can't pay it but it will be -0.47 , but i'm not sure because i don't speak English

Step-by-step explanation:

12.10 - 12.57 = -0.47

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.

homozygous. one is homozygous, while two is heterozygous.
