$\left(4x^3\:+\:3x^2\:-\:6x\right)\:-\:\left(10x^3\:+\:3x^2\right)$

[ open brackets ]

$\left4x^3\:+\:3x^2\:-\:6x\right\:-10x^3 - 3x^2$

[ group terms ]

$4x^3-10x^3+3x^2-3x^2-6x$

[ final answer ]

$-6x^3-6x$ .......this is a polynomial as it contains variable, coefficients.

Answer:

10 > v (if you don't trust me, check it yourself. Subsitute v for 10 in the first equation.

Step-by-step explanation:

1) 7 > v - 3

2) add 3 to both sides

3) so 7 plus 3 equals 10

So you basically do this

7 > v - 3 (ad 3 to both sides)

You get 10 > v (which is as simplified as possible)

Hope this helps! :)

50 POINTS!! PLEASE ASAP. The director of a local ballet company needs to print the programs for the next performance. Janet’s Pr

Maru [420]

For this case we find the expression that represents the cost of each printing press.

x: Be the variable that represents the number of programs to print

So:

Cost 1: Janet’s Print Shop

$C (x) = 0.25x + 35$

Cost 2: The Printing Press

$C (x) = 0.15x + 50$

If we want to find the number of programs for which the costs are the same, then we equate both equations:

$0.25x + 35 = 0.15x + 50\\0.25x-0.15x = 50-35\\0.1x = 15\\x = \frac {15} {0.1}\\x = 150$

Thus, for 150 programs the cost is the same.

Answer:

For 150 programs the cost is the same.

(13p5 + 6p - 12p2) - (-9p - p2 - 13p5)

anastassius [24]

Answer:

Step-by-step explanation:

13p⁵ + 6p - 12p² -(-9p - p² - 13p⁵) = 13p⁵ + 6p - 12p² + 9p + p² + 13p⁵

{Distribute (-1) to the second expression}

= 13p⁵ + 13p⁵ -12p² + p² + 6p + 9p

{Combine like terms}

= 26p⁵ - 11p² + 15p
