Five pounds of fudge sells for $17.00. At the same rate, how much will 12 pounds of fudge cost?
A) $34.60
B) $40.80
C) $42.40
D) $51.00

option B is correct

Step-by-step explanation:

If five pounds of fudge = $17.00

One pound will equal 17.00/5 = $3.40

If one pound of fudge equals $3.40, at the same rate, twelve pounds will cost:

$3.40 × 12= $40.80

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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.
