Here if this helps your welcome if not I’m sorry

So start with

2x2+3x-5=0

2x2=4

4+3x-5=0

Subtract 4 from both sides

4+3x-5=0
-4. -4

The 4 cancels out

3x-5= -4

Now add 5 to each side and the 5 will cancel

3x-5=-4
+5. +5

3x=1

Divide 3 from both sides the 3 cancels

3x=1

3/3x= 1/3

So your answer is:
x=1/3

Where does 3.5 belong on the Venn diagram?
shtirl [24]

Answer:

C) Rational Numbers

Step-by-step explanation:

Integers include all whole numbers both negative and positive. This is basically just any number without a decimal, and since 3.5 has a decimal, it can't be an integer.

Natural numbers also don't include numbers without decimals. They only include whole numbers that a positive.

Irrational numbers have a repeating decimal that cannot be represented as a fraction. However, we know that 0.5 can be represented as 1/2

A rational number is a number that can be in the form p/q , where p and q are integers and q is not equal to zero. We can change 3.5 to be in the form p/q by changing it to be an equivalent improper fraction of 7/2
