Which equation represents this situation? five less than a number is equal to three times the sum of the number and two? a.) 5 - x = 3x + 2 b.) x - 5 = 2x + 3 c.) x - 5 = 3(x + 2) d.) 5 - x = 3(2x)

I would say...

C.)x - 5 = 3 (x + 2)

Really really sorry if I'm wrong...

One thing I can say is that when it says 5 less than a #, that means the # is being subtracted from another #...

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

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.
