( 3X^2 - 5)( 4x^3 +7x + 2).

Mathematics

Answer:

12x^{5} + x³ + 6x² - 35x - 10

Step-by-step explanation:

(3x² - 5)(4x³ + 7x + 2)

Each term in the second factor is multiplied by each term in the first factor, that is

3x²(4x³ + 7x + 2) - 5(4x³ + 7x + 2) ← distribute parenthesis

= 12x^{5} + 21x³ + 6x² - 20x³ - 35x - 10 ← collect like terms

= 12x^{5} + x³ + 6x² - 35x - 10

-2 =5 - 7x how do you do this
Paul [167]
First you want to get x by it’s self so you need to get ride of your 5 so you subtract 5 on both sides leaving you with -2 and -5 on the same side then you combine those two number to get -7 now to get your x all you have to do is divide both sides by -7 since your x is -7 once once your x is now by its self but on the other side -7 divided by -7 equals 1 bc 7 goes into 7 once and it turns positive because anytime you divide an negative number by a negative number it turns into a positive number so your answer over all is 1=x

You have 29 thirds. This is a fraction greater than one.
hichkok12 [17]

You could make 9 wholes with that and there would be 2 thirds left over.

To solve it you would just have to divide 29 by 3 which would give you 9 and leave you with 2 thirds left.
