There are some nickels and dimes in a large piggy bank. For every 2 nickels there are 3 dimes. There are 100 coins total. How many of each coin are in the piggy bank? help

answer: 2 and 1

step-by-step explanation: got this question

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.

c - they will have the same distribution

this is the only one that could make sense. : )
