Answer:
Option D: -2x-10 is the correct answer.
Step-by-step explanation:
Given expression is;
-2 (x+5)
We will solve the expression by multiplying -2 with the terms inside the brackets.
Therefore,
Multiplying -2 with the terms
-2*x + 5* -2
-2x + (-10)
-2x - 10
Hence,
Option D: -2x-10 is the correct answer.
0.81 = 81/100
0.5 = 5/10 = 1/2
0.63 = 63/100
0.214 = 214/1000 = 107/500
