Answer:</h3>
x = 4; y = 9; length of a side = 5
<h3>
Step-by-step explanation:</h3>
Here, you're expected to use the fact that all of the sides of a square are the same length.
The left and right sides both have different expressions only in y, so it is convenient to equate them.
... y -4 = 2y -13
... 0 = y -9 . . . . . subtract the left side
... 9 = y . . . . . . . add 9
This tells us the side of the square (s) is ...
... s = y -4 = 9 -4
... s = 5
And we can use this to find x.
... 5 = 2x -3 . . . . equate the x-expression to the square side length
... 8 = 2x . . . . . . add 3
... 4 = x . . . . . . . . divde by the coefficient of x
x and y are 4 and 9; the square side length is 5.
Your answer would be a) 60 - x°. This is because angles in a triangle add up to 180°, and as angle B is 90 and angle C is x + 30, that means angle A must be 180 - (90 + 30 + x) which is 180 - (120 + x), which when simplified equals 60 - x. I hope this helps!

<h2>Given:
</h2>
<h2>
Step-by-step explanation:</h2>
In this problem, we need to find the value of the given expression for which we need to simplify the given expression.
We need to solve the numbers within the parentheses.
We can bring the constant one side and variables another side.
Taking fourth root for ‘8’ and ‘3’ will give numbers which are very tough to solve further.
Since, we cannot solve the above equation further. The value of the given equation remains,
Answer:
X = 5/12
Step-by-step explanation:
(-1/3) = X - (3/4)
(-4/12) = X - (9/12)
+(9/12) +(9/12)
5/12 = X
