Answer: K=2
Step-by-step explanation:
-8k+6=-10k+10
+10k
2k+6=10
-6
2k=4
k=2
Its 3 cause 160 x 4 is 640 , so 643 - 640 is 3 so the answer of the problem is 3

Answer: 38
Step-by-step explanation: to evaluate an expression for these variables, plug in those numbers for the variables.
Plugging in -1 for y and -19 for z gets you this:
-2(-1)^2(-19)
Now simplify according to order of operations (PEMDAS - parenthesis exponents multiplication/division addition/subtraction)
-1^2 = 1
-2(1) = -2
-2(-19) = 38
Your answer is 38
