Answer:
the second option is solution
Step-by-step explanation:
exponents inside parentheses get multiplied by exponents outside them
so first: x^-9y^6 divided by x^12y^18
next, when dividing like terms, keep variable and subtract their exponents
-9 - 12 = -21
6 - 18 = -12
Don't leave negative exponents as answer, simplify by putting them into the denominator (where the exponents will now become positive) with 1 as numerator
-2(x+13) + 37 < 5x -17
-2x - 26 + 37 < 5x -17
-2x + 11 < 5x - 17
28 < 7x
x > 4
It is true that bad road condition does have a direct impact
on the physical, emotional and economic aspects to the family, the community
and the country. Bad roads can cause accidents which directly impacts a person
physically. Mentally it is very stressful for a person to drive on bad roads. He
or she has to be extra careful regarding potholes and other damages that have
happened to the road. Economically bad roads can be the reason for price rise
of products as time required to move a product via road is more. Also the cost
of transport increases drastically.
