Answer:
domain is:(-∞,-3]∪ [3,∞)
Step-by-step explanation:
f(x)=√(x²-9)
f(x)=√(x-3)(x+3)
domain is:(-∞,-3]∪ [3,∞)

1 answer:
:1
i didnt understand the question because of my English sorry
:2
we all know that the total of degrees is 180 so 70+70=140
180-140=40
so the answer is 40
3:
we have a figure with 4 angle so the total of degrees is 360 so the answer is 126
4:
the answer most be 50 becuse we have a Special degree witch always equal 90 if we have recatngle so
x+40=90
X=50 the answer and if you want to try again choose the second one
2x-10=90
2x=100
X=50 same answe you see

Answer:
(16 - 8 × 2 ÷ 4 + 6) ÷ 3 = 6
Step-by-step explanation:
The given expression is (16 - 8 × 2 ÷ 4 + 6) ÷ 3
We will solve this expression by using BODMAS rule,
B - Bracket (Parenthesis)
O - Order (exponents)
D - Division
M - Multiplication
A - Addition
S - Subtraction
(16 - × 2 ÷ 4 + 6) ÷ 3
We will solve the expression inside the parenthesis first followed up by the exponents,
(16 - × 2 ÷ 4 + 6)
= (16 - 8 × 2 ÷ 4 + 6)
Then Divide,
= (16 - 8 × + 6)
Then multiply,
= (16 - 4 + 6)
Further addition,
= (22 - 4 )
At last subtract,
= (18)
Now put the solution of the parentheses in the expression,
= (18) ÷ 3
= 6
Therefore, solution of the given expression will be 6.
