The side with all the 9s and x is 12 just like its opposite side because this is a parallelogram. We can write the equation to add up the three segments; the ones on the left and right are 9-x:
9-x + x + 9-x = 12
18 - x = 12
x = 6
The answer is a.w+9 because it means the w plus 9 more it the same as 9 more than w

The difference is the result of a subtraction problem.
We are given two values that are being subtracted: 54 and a number, represented by

Answer:
a⁴b⁴ - c⁴
Step-by-step explanation:
The difference of squares formula states that (a - b)(a + b) = a² - b². In this case, a = a²b² and b = c² so a² - b² = (a²b²)² - (c²)² = a⁴b⁴ - c⁴.
