Every absolute value MUST be 0 or greater (positive); thus, <span>| 5x + 13| = -7 has no solution due to the - number on the right.

Answer:
K(-1)=6
Step-by-step explanation:
t=-1
2 times -1 squared
-1 squared=1
2x1 = 2
2+4=6
K(-1)=6

Answer:
C
Step-by-step explanation:
The sum of the polynomials (8x²-9y²-4x)+(x²-3y²<span>-7x) is:
1. You must add the terms whose variables and exponents are the same.
2. Let's rewrite the polynomials:
</span>
(8x²-9y²-4x)+(x²-3y²-7x)
8x²-9y²-4x+x²-3y²-7x
(8+1)x²+(-4-7)x+(-9-3)y²
3. Therefore, the result is:
9x²-11x-12y²
3. <span>What is the sum of the polynomials?
The answer is: </span>9x²-11x-12y²
