Simple expressions use the arithmetic operators + and *, with both numbers and variables allowed as operands. the recursive definition of such expressions is as follows:

1) Any number or letter (i. e., a variable) is an expression.

2) if E and F are expressions, then so are E+F, E*F, and (E)

For example, both 2 and x are expressions by the basis. The inductive step tells us x+2, (x+2), and 2*(x+2) are all expressions. Notice how each of these expressions depends on the previous ones being expressions. Prove that every expression has an equal number of left and right parentheses.

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

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.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
