(4u^3+6u^2+7)+(6u^3-2u+7)
simplify the sum'

Hi Nova

(4u³+6u²+7)+(6u³-2u+7)

= 4u³+6u²+7+6u³-2u+7

Combine like terms

( 4u³+6u³)+(6u²)+(-2u)+(7+7)

= 10u³+6u² -2u+14

There no like terms so you can not simplify the sum

I hope that's help and if you have questions please ask !

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
