Answer:
x = 
Step-by-step explanation:
We know that;
The triangle is isosceles, and the hypotenuse is x, the un-labeled side is 5.
Therefore we can say;
5² + 5² = x²
25 + 25 = x²
50 = x²
= x
We can simplify this further;
=
=
Hope this helps!
Answer:
12
Step-by-step explanation:
30+(4x+2)=8+6x
30+4x+2=8+6x
32+4x=8+6x
32=8+6x-4x
32=8+2x
2x=32-8
2x=24
x=24/2
x=12
We can not really tell in this question as you dont know the equation that is being used for the domain and range relationship but overall one should know that:
The set of values of the independent variable(s) for which a function or relation is defined as the domain of a function. Typically, this is the set of x-values that give rise to real y-values.
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
