Answer:
x=1
Step-by-step explanation:
So, first you make sure to multiply the parenthesis by the negative so then it would be,
-x-3=2x-6
Then you add the -3 from the right to the other side
so, -x=2x-3
Then you want all the X variables to one side so you subtract the 2x to both sides.
so, -3x=-3
divide both by -3
x=1
The answer is 18 . Because 36 divided by 2 is 18
Answer:
Step-by-step explanation:
step 1
Find the length side c
Applying the law of sines

substitute he given values

solve for c

step 2
Find the measure of angle B
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so

substitute the given values

step 3
Find the area of the triangle
we know that
The area of the triangle applying the law of sines is equal to

substitute the given vales

The answer would be x^4 -16
Explanation: use the FOIL method.
(x^2 +4)(x^2 -4)= x^4 +4x -4x -16. 4x and -4x cancel each other out. You are left with x^4 -16.
