Joe purchased a 42" flat screen tv for his recreation room. the tv was originally
priced at $2,549. the sale price was $1,910. what was the percent of discount?
a 25%
b 30%
c 35%
d 250

A (close examination)

Step-by-step explanation:

25% of 2549 = 637.25 (Rounding this to nearest whole number)

2549 - 637 = 1912

1912 doesn't equal 1910 even though it is slightly off by a couple of dollars

A is correct

30% of 2549 = 764.7 (Round this to nearest whole number)

2549 - 765 = 1784

1784 doesn't equal 1910

B isn't correct

35% of 2549 = 892.15 (Round this to Whole Number)

2549 - 892 = 1657

1657 doesn't equal 1910

C isn't correct

2549 - 250 = 2299

2299 doesn't equal 1910

D isn't correct

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

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.
