Which expression is equivalent to x2(3x3−2x)−(−7x3+2) ? 3x5+5x3−2 3x5−9x3+2 3x5+7x3−2x+2 3x6+7x3−2x2−2
erik [133]

Answer:

The equivalent expression is 3x^5-9x^3-2

Step-by-step explanation:

To find the equivalent expression, we need to

open up the brackets;

Thus;

x^2(3x^3 -2x) - (7x^3 + 2)

= 3x^5 -2x^3 -7x^3 -2

= 3x^5 -9x^3-2

If Maria can buy 12 lemons for $2.40, how much will it costs her to buy 16?Set up a proportion to solve.
IgorLugansk [536]
2.40/12 = x/16
then that would mean 12x= 2.40(16)
which equals 12x= 38.4, then divide 12 by both sides, getting you 3.2 so the answer is it would cost her $3.20 cents to by 16 lemons

Find a degree 3 polynomial with real coefficients having zeros 3 and 3−3i and a lead coefficient of 1. Write P in expanded form.
LekaFEV [45]

Answer:

P =  x³ − 9x² + 36x − 54

Step-by-step explanation:

Complex roots come in conjugate pairs.  So if 3−3i is a zero, then 3+3i is also a zero.

P = (x − 3) (x − (3−3i)) (x − (3+3i))

P = (x − 3) (x − 3 + 3i) (x − 3 − 3i)

P = (x − 3) ((x − 3)² − (3i)²)

P = (x − 3) ((x − 3)² + 9)

P =  (x − 3)³ + 9 (x − 3)

P =  x³ − 9x² + 27x − 27 + 9x − 27

P =  x³ − 9x² + 36x − 54
