Step-by-step explanation:
Answer:
x^3 + x^2 + x
Step-by-step explanation:
3x^3 + 4x^2 − (2x^3 + 3x^2 − x)
Distribute the Negative Sign:
=3x^3 + 4x^2 + −1 (2x^3 + 3x^2 − x)
=3x^3 + 4x^2 + −1 (2x^3) + −1(3x^2) + −1 (−x)
=3x^3 + 4x^2 + −2x^3 + −3x^2 + x
Combine Like Terms:
=3x^3 + 4x^2 + −2x^3 + −3x^2 + x
=(3x^3 + −2x^3) + (4x^2 + −3x^2) + (x)
=x^3 + x^2 + x
Answer:
-7
Step-by-step explanation:
To find the differences in a sequence, subtract the term before:
-15 -(-8) = -7
-22 -(-15) = -7
These differences are the same, so constitute the "common" difference.
The common difference of the sequence is -7.
Answer:
3000
Step-by-step explanation:
Answer:
Step-by-step explanation:
1) a ) 7x = 56
Divide both sides by 7
7x/7 = 56/7
x = 8
2) 6y = 35
Divide both sides by 6
6y/6 = 35/6
