in advance

This answer isn't listed, but likely choice B seems to be the closest. Check to make sure there aren't any typos.

How did I get that answer? Well the phrase "product of 8 and x" means "8 times x" or simply 8*x. The asterisk means "multiply". Often we can drop the asterisk to say 8x and mean the same thing. Multiplication is implied here.

"sum of 5 and product of 8 and x" turns into "sum of 5 and 8x" which becomes 5+8x

Finally, the term "quotient" is the result of a division. We will divide 9 over all of (5+8x). I use parenthesis so we know that everything but the 9 is in the denominator

That's how we end up with the answer 9/(5+8x)

Or you can say "9 over (5+8x)" or something along those lines. The slash bar is often used for fractions and division.

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
