Answer:

Explanation:
Here, we want to get the value of x and y
From the given image, the angle y and 116 lie on a straight line
The sum of the angles on a straight line is 180 degrees
Thus:

The sum of the internal angles of a polygon can be calculated by the formula:

where n is the number of sides the polygon has
In the case of the given question, n is 4
Substituting the value of n, we have it that:

To get the value of x:
Answer:
5xy
Step-by-step explanation:
I'm going out on a limb and assuming exponents.

We can note that 5 is a common factor for the coefficients. All the terms share at least one x. All the terms share all least one y. So the GCF of these monomials is 5xy.

Answer:
record 6 hundredths; add 4 to the numbers of tenths
Step-by-step explanation:
Nicholas needs to write down the 6 and "carry" the 4, adding it to the numbers of tenths.
Depending on the method you've been taught, the 4 may be written above the column with place value of tenths, or it may be written on a separate sum line.
