3 0

Answer: x= -7

Step-by-step explanation: subtract 4x on both sides. That leaves you with -9=3x+12. Then subtract 12 on both sides. From there you have -21=3x. Divide by 3, and your answer is negative 7

Answer:

8 - $8\sqrt{3}$

Step-by-step explanation:

For this problem you have to use the 45-45-90 triangle theorem and 30-60-90 theorem.

For 45-45-90, the isosceles sides = 4, so the hypotenuse of the 30-60-90 triangle is 4 times 2, which is 8. If x is 8, then since y is the side across from the 60 angle, y is $8\sqrt{3$ . Since this really can't be simplified after y is subtracted from x, the final answer is just 8 - $8\sqrt{3}$ .
