Perimeter is the sum of all three sides so in this case x+(3x+2)+(3x+2).
They also gave us the perimeter which is 39 so
39= x+(3x+2)+(3x+2)
Simplify so 39=7x+4. [x+3x+3x=7x and 2+2=4]
Then get x by itself so subtract 4 from both sides.
35=7x
Then divide both sides by 7 to get x by itself.
Which leaves us with
X=5
Assume a statement true and then show it must be false.

Answer:
1599995904
Step-by-step explanation:
first, you must do the top part of the fraction. you can start by doing the power numbers such as 2 power 4, 4 power 6 and 4 power 4.
the complete answer for the top part is: 12x 16x 4069x 8x 2x 256 which equals: 3199991808
then, you must divide by 2 which gives you the answer of: 1599995904
Answer:
1/64
Step-by-step explanation:
Each of the questions has 4 choices, making the chance to get the correct answer 1/4. So, to get 3 questions correct, you can use 1/4^3 to find the probability. So, the answer is 1/64.
