since T is the midpoint of SU, then ST = TU.

Answer:
18
Step-by-step explanation:
I did my method that I was taught but if you do (-5) - (-2), you get 3. So you subtract 39 by the -21 to get 18.
Answer:
It'd be a rational number
Step-by-step explanation:
<em>Real numbers are a set of numbers containing all of the rational numbers and all of the irrational numbers. </em>
Types of numbers <u>in the rational number "section" are decimals, whole, mixed, and fraction numbers whether they are negative or positive they are rational numbers.</u>
Irrational numbers are numbers that cannot be expressed as the ratio of two integers. So they would be square root, pi and more.
Answer:
A quadrilateral. A square. A Parallelogram
Step-by-step explanation:
A quadrilateral is a polygon shape with four sides and four angles. The interior angle of a quadrilateral sums up to 360°.
A parallelogram is a quadrilateral (has four sides and four angles) in which has two pair of opposite sides are parallel to each other.
A square is a quadrilateral with four equal sides consisting of two pair of parallel sides. Each angle in a square measures 90°. A square is a quadrilateral and a parallelogram.
From the question, we can see in the image attached that the shape is a square since all its sides are equal, hence it is also a quadrilateral and a parallelogram.
