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
Answer:
30
Step-by-step explanation:
6+9= 15, 15x2=30
Answer:
1/x+5
Step-by-step explanation:
1. Rewrite 3x as a difference
x-2/x^2 + 5x-2 - 10
2. Factor out x from the equation, then factor out -2.
x-2/ x+(x+5) - 2(x+5)
3. Factor out x+5 from the expression
x-2/ (x+5)(x-2)
4. Reduce the fraction with x-2
x-2 / (x+5) x-2
1/x+5
Tara needs to read 81 pages by next friday.
First, divide the pages of the book by 5.
203 ÷ 5 = 40.6
Then, multiply the answer by 2.
40.6 x 2 = 81.2
Now, round down.
81 pages.
