Answer:
Step-by-step explanation:
A parallelogram is a quadrilateral (4-sided polygon) that has two pairs of parallel sides.
In this sense, this figure shows a especial parallelogram called <u>rectangle</u>, since its four sides form right angles ().
Hence:
So, the correct choices among the given options are:
Let's call this unknown number, x.
So we know that 4 and this number, x, are going to be added together and 6 is going to be subtracted from it. Therefore we can write the expression:
Since we cannot proceed any further without knowing either the value of x or what the expression equals, this is as simplified as it can be.
