3+c - (4+c)
pretend that there is a -1 in front of the bracket
3+c-1(4+c)
multiply the bracket by -1
(-1)(4)=-4
(-1)(c)=-c
3+c-4-c
3-4+c-c ( combine like terms)
+c-c=0
3-4=-1
-1+0=-1
Answer:
-1
Answer:
A choice.
Step-by-step explanation:
Irrational number is a number that cannot be written in a fraction form. All square roots are classified as an Irrational number unless can be evaluated to Rational number.
From A choice, you cannot evaluate the square root of 7 into any rational number. Therefore, it is an Irrational number.
B choice, even though there is a square root, but you can still evaluate from square root of 4 to 2.
For C and D, both are integers. Integers are classified to be Rational Number. Therefore, C and D both are rational.
