To simplify the given expressions and find the correct answers, follow these steps:
1.6g + 8k - 9g + 2k:
Combine like terms:
(1g - 9g) + (8k + 2k) = -8g + 10k
Answer: -8g + 10k
3g + 10k:
The expression is already simplified.
Answer: 3g + 10k
-3g + 10k:
The expression is already simplified.
Answer: -3g + 10k
17gk:
The expression is already simplified.
Answer: 17gk
10k - 3:
The expression is already simplified.
Answer: 10k - 3
-4x + 6x^2 + 5x:
Combine like terms:
(-4x + 5x) + 6x^2 = x + 6x^2
Answer: x + 6x^2
7x^3:
The expression is already simplified.
Answer: 7x^3
6x^2 + 9x:
The expression is already simplified.
Answer: 6x^2 + 9x
6x^2 - 9x:
The expression is already simplified.
Answer: 6x^2 - 9x
6x^2 + x:
The expression is already simplified.
Answer: 6x^2 + x
a^2 + 5a - 3a^2:
Combine like terms:
(a^2 - 3a^2) + 5a = -2a^2 + 5a
Answer: -2a^2 + 5a
5a + 2a^2:
The expression is already simplified.
Answer: 5a + 2a^2
-2a^2 + 5a:
The expression is already simplified.
Answer: -2a^2 + 5a
-3a^2 + 6a:
The expression is already simplified.
Answer: -3a^2 + 6a
5a - 3a^2:
The expression is already simplified.
Answer: 5a - 3a^2
3x^2 + 8x + 7x:
Combine like terms:
(3x^2 + 15x)
Answer: 3x^2 + 15x
18x^3:
The expression is already simplified.
Answer: 18x^3
3x^2 + 1:
The expression is already simplified.
Answer: 3x^2 + 1
3x^2 - x:
The expression is already simplified.
Answer: 3x^2 - x
To find the degree of a polynomial expression, identify the highest exponent of the variable:
-5w - 4w^2 + 7w + 16:
The highest exponent of w is 2 in the term -4w^2.
Answer: 2
