D.circle
D

Lexie is 12 years old and is 4 years older than Felix.Felix is 5 years younger than Ivan.Ivan is 2 years older than Chung.Which lists the students in order from oldest to youngest?
A.Ivan,Lexie,Chung,Felix
B.Lexie,Felix,Ivan,Chung
C.Ivan,Chung,Lexie,Felix
D.Felix,Lexie,Ivan,Chung
B?

for number 1 the answer is D and number 2 A

Your first answer is right, but second is wrong.

Write down the age of each kid.

Lexie - 12
Felix - 8

etc.

Lexie=12

Felix-8
Ivan-13
Chung-11
A?

Yes, you and Posidon are right. # 2 is A.

To determine which shape cannot have perpendicular lines, we need to understand what perpendicular lines are. Perpendicular lines are two lines that intersect at a 90-degree angle.

A triangle can have perpendicular lines. For example, a right triangle has one 90-degree angle, and the sides opposite the right angle are perpendicular.

A pentagon can have perpendicular lines. If the pentagon is not concave and has at least one right angle, it can have perpendicular lines. An example is a regular pentagon with one of its angles measuring 90 degrees.

A trapezoid can have perpendicular lines. If the trapezoid is an isosceles trapezoid, it can have perpendicular diagonals.

A circle cannot have perpendicular lines. By definition, a circle is a set of points equidistant from a single center point. A circle is curved and does not have any straight lines or angles. Therefore, it does not have perpendicular lines.

Therefore, the correct answer is D. Circle is the shape that cannot have perpendicular lines.

To determine the order of the students from oldest to youngest, we need to analyze the given information:

1. Lexie is 12 years old and is 4 years older than Felix.
2. Felix is 5 years younger than Ivan.
3. Ivan is 2 years older than Chung.

Let's apply this information step by step:

From statement 3, we know Ivan is older than Chung.
From statement 2, we know Felix is younger than Ivan.
From statement 1, we know Lexie is older than Felix.

Combining these statements, we can determine the order of age from oldest to youngest:

Ivan, Lexie, Felix, Chung.

Therefore, the correct answer is A. Ivan, Lexie, Chung, Felix.
