2(9x-1)+7(x+6)=-60
Reorder the terms in parentheses
+(+18x-2)+7*(x+6)=-60
Remove unnecessary parentheses
+18x-2+7*(+x+6)=-60
Reorder the terms in parentheses
+18x-2+(+7x+42)=-60
Remove unnecessary parentheses
+18x-2+7x+42=-60
We move all terms containing x to the left and all other terms to the right
+18x+7x=-60+2-42
We simplify left and right side of the equation
+25x=-100
We divide both sides of the equation by 25 to get x
x=-100/25
x=-4
A and B cannot be the answer because they are square equations and not linear. C also is not the answer because you can't make m/a = something
D is the answer because you can divide both sides by I and get equation
V/I=R. Right side is linear therefore that is the answer.
Answer:
depends
Step-by-step explanation:
If you mean just -12.161616, then it’s rational.
If you mean recurring decimal, then it’s not.
