3-33-4=-34

**Answer:**

g = 1/2

**Step-by-step explanation:**

4 is the product of 8 and g.

=> 8*g = 4

=> g = 1/2

**Answer:**

irrational

**Step-by-step explanation:**

what are rational numbers ?

every number that can be expressed as a/b, with a and b being integer numbers, and b different to 0.

the square root of any number that is not a squared rational number is then an irrational number.

I am not sure, if the expression here is

sqrt(13) + 4

or

sqrt(13 + 4), which would then be sqrt(17).

but in both cases we are creating the square root of a not- squared rational number.

neither 13 nor 17 are the result of a multiplication of a rational number with itself.

in fact, 13 and 17 are prime numbers with no other factors than either 1 or themselves.

so, both, sqrt(13) and sqrt(17) are irrational numbers.

adding or subtracting rational numbers to irrational numbers result again in irrational numbers.

**Answer:**

2 or 3

**Step-by-step explanation:**

**Answer:**

14/39 or 35.9%

**Step-by-step explanation:**

We have a total of 39 students and 14 of which study both Art and Biology

and the rest of the total is unimportant to the question. Since there are 14 students out of 39 we can now do the math and figure out that 14 divied by 39 is right about 35.9 percent.
