Hi there!
Everything looks correct except for the step to get to -6x < 36. Here you put multiplication property of order, and to get here you have to add 30 to both sides, so it would actually be the addition property of order.
I hope I helped!

Answer: Domain of function is
or (0,
)
Step-by-step explanation:
Assuming x as width of rectangle
so, Width = x
Question says, Length is 5in more than 3 times id width.
we write as Length = 3x+5
Therefore, Area of rectangle will be given function f(x)
f(x) = x(3x+5)
Here, It is important to notice that width and length of rectangle will always be positive values and also, area of rectangle is always positive.
we can write in equation as


Thus, Domain of function is
or (0,
)
Answer:1
Step-by-step explanation:
It's an isosceles triangle, which means base angles are equal.
48 = 6x
48/6 = x
8 = x
48 = 48
Angle y = 180° - (48° + 48°)
Angle y = 180° - 96°
Angle y = 84°
The two missing angles are 48° and 84°.
