Answer:
I believe that 4 1/2 divided by 6 is the correct answer.
(It is the same as the expression you wrote next to "Regular." It is correct because it does not include an equal sign and correctly expresses the problem.)
Note: Do not include any work below the arrow when writing in the "Expression" section.
Please let me know if this is incorrect.
Answer:
Option A.,
Step-by-step explanation:
(5x3− x + 14) − (3x2− 9x + 4)
First remove the 2 sets of parentheses. Note when we remove the second one we multiply the terms inside by -1. ( Or we might say we distribute the negative over this parentheses.)
= 5x^3 - x + 14 - 3x^2 + 9x - 4
Now we simplify like terms:-
= 5x^3 - 3x^2 + 8x + 10 (answer).
Everything is in million acres, so we can just drop that while we work it out but just remember we have to add it back on at the end of the problem.
First year 3.42
Second year 8.71
Third year ???
Total 21.46
So...
3.42 + 8.71 + ? = 21.46
12.13 + ? = 21.46
? = 21.46 - 12.13
? = 9.33
The 3rd year 9.33 million acres were burned
*Note I put a ? for the unknown. I could have used x or y or anything else.
3x^2+5x-2=?
I think,,,,,
=>3x^2+5x-2=0
=>3x^2+3x+2x-2=0
=>3x(x+1)-2(x+1)=0
=>(3x-2)(x+1)
///////////////??///////////
=>x=2/3 & x= -1
Forgive me if wrong
The least common denominator is 12.
1 * 3 = 3
4 * 3 = 12
1 * 4 = 4
3 * 4 = 12
4+3/12
7/12x is the final answer.
