(10x^4-2x 7)-(6x^4+2x^3-4x^2-1)

Mathematics
1 answer:
Lerok [7]3 years ago
3 0

Hello from MrBillDoesMath!

Answer:

4x^4 - 2x^3 + 4x^2 -2x + ( +\-7 + 1)

See Discussion for meaning of "+\-" symbol above

Discussion:

** The first polynomial (10x^4-2x 7)    is missing an operand between 2x and 7. I have indicated it below by using (+\_), meaning I don't know what you wanted.**

(10x^4-2x +\- 7)-(6x^4+2x^3-4x^2-1)      => combine like terms

(10x^4 - 6x^4) - (2x^3) - (-4x^2) + (-2x) + ( +\-7 +1) =

4x^4 - 2x^3 + 4x^2 -2x + ( +\-7 + 1)

Thank you,

MrB

Q15. Ken earned x dollars at his part-time job on Friday. His wife earned $12 more
mafiozo [28]

Ken earns 54 dollars at his part-time job on Friday

Given that Total amount earned by ken and his wife at their part-time job on Friday= $174

Money earned by ken= x dollars

Money earned by ken's wife = (2x+12) dollars

Total amount earned by ken and his wife at their part-time job on Friday=  x dollars + (2x+12) dollars

(x + 2x + 12 ) dollars = $ 174 ( addition of ken and ken's wife income and total amount earned by ken and his wife at their part-time job on Friday is $174)

(3x + 12 ) dollars = $ 174

3x=$162

x=\frac{162}{3}

x= 54 dollars

Therefore,54 dollars were earned by ken  at his part-time job on Friday

Hence,Ken earns 54 dollars at his part-time job on Friday

5,-30,180,-1,080 what are the two next numbers
Sedbober [7]

Answer: The next two numbers are 6,480, -38,880.

Step-by-step explanation:

The pattern is to multiply each consecutive term by (-6).  Understand that a negative number times a positive number is a negative number (eg: 5 x - 6 = -30).

A negative number times a negative number is a positive number

(eg: -30 x -6 = 180).  Also, (-1,080 x -6 = 6,480.)  (6,480 x -6 = 38,880).

Hope this helps.
