Use BODMAS
Brackets first 2-4 = -2
Then divide
-2/-2 =+1
then subtract, plus minus becomes minus
30 -+1 = 29

Is this a function idk also what's the domain and range

masya89 [10]

This is a function since it passes the vertical line test. It is impossible to draw a single vertical line to have it pass through more than one point on the curve.

The domain is the set of numbers x such that x is between -3 and +3 excluding those endpoints. In other words, the domain is -3 < x < 3. We never actually get to either endpoint because of the vertical asymptotes.

The range is the set of all real numbers. It is possible to get any output we want depending on the specific input.

Answer: Exactly square root 58 inches

Step-by-step explanation: The dimensions given for the right angled triangle are 7 inches and 3 inches respectively. The third side is yet unknown. However what we know is that a right angled triangle can be solved by using the Pythagoras theorem which states that,

AC^2 = AB^2 + BC^2

Where AC is the longest side. The question requires us to calculate the longest side and with the other two sides already known, the Pythagoras theorem now becomes,

AC^2 = 7^2 + 3^2

AC^2 = 49 + 9

AC^2 = 58

Add the square root sign to both sides of the equation

AC = square root 58 inches
