Answer: 8x+12
Step-by-step explanation:
perimeter equals (x+4) + (3x+2) + (x+4) + (3x+2) = x+4 + 3x+2 + x+4 + 3x+2 = 8x+12
Answer:
17.3
Step-by-step explanation:
To solve this equation, you need to use the pythagorean theorem which is:

a= length
b= height
c= hypotenuse
First, substitute in your values for the equation:

Then, use the squares in the equation:

Then, subtract 100 from both sides to isolate b:

Finally, square root both sides to get your answer:

Then round to the nearest tenth which gives you 17.3.
Answer:
Step-by-step explanation:
0 - 9p = 0
9p = 0
p = 0
Your answer would be x = 12
The triangle sum theorem states that the 3 angles in a triangle equal 180.
Since we have a 90 degree angle shown, we can add it to the other two and set it equal to 180.
30+90+6x-12=180
108+6x=180
6x=72
x=12
