Hello from MrBillDoesMath!
Answer:
3,000
Discussion:
Think in terms of thousands:
1000
2000
3000
<- 3376
4000
Notice that 3376 is closer to 3000 than 4000 so 3376 rounded to the nearest thousand is 3000.
Thank you,
MrB
1.
3 x 4 = 12
3 + 4 = 12
The two integers a and b are : 3 and 4
2.
-4 x 1 = -4
-4 + 1 = -3
The two integers a and b are : -4 and 1
3.
-3 x -3 = 9
-3 + -3 = -6
The two integers a and b are : -3 and -3
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
Part A: x^2 + 5x - 8
Part B: 5x^3 + 3x^2 - 6x + 5
Step-by-step explanation:
Part A:
To find the total of side 1 and 2, add the two expressions which represent each side. Combine like terms to simplify.
3x^2 − 2x − 5 + (7x - 2x^2 − 3)
3x^2 - 2x^2 -2x + 7x -5 + -3
x^2 + 5x - 8
Part B:
To solve for the third side of a triangle using its perimeter, subtract the lengths of two of its sides from its perimeter. The perimeter is 5x^3 + 4x^2 − x − 3. Subtract 3x^2 − 2x − 5 and 7x - 2x^2 − 3. The remaining expression is the third side. Combine like terms to simplify.
5x^3 + 4x^2 − x − 3 - (3x^2 − 2x − 5) - (7x - 2x^2 − 3)
5x^3 + 4x^2 - x - 3 - 3x^2 + 2x + 5 - 7x + 2x^2 + 3
5x^3 + (4x^2 -3x^2 + 2x^2) + (-x + 2x - 7x) + (-3 + 5 + 3)
5x^3 + 3x^2 - 6x + 5
