Answer:
x = 6
y = 24
z = there is no z?
Step-by-step explanation:
All angles of a polygon add up to 360 degrees
The 2 parellel lines on top and bottom mean that there are 2 right angles on the left side
3y + 18 = 90
3y = 72
y = 24
15x + 30 + 10x = 180
25x = 150
x = 6
465•10-5
(That -5 is suppose to be an exponent
Explanation:

The line of the first part of the function, without the restriction of x <=-2:
The line of the second part of the function, without the restriction is:
To graph the full function, we have to draw a line over the green dashed line until x = -2 and then continue drawing but now over the orange dashed line
Answer:
The graph of the function is:
• Domain:
I think it would be 27.38ᴹ2
