Step-by-step explanation:
5 lines of symmetry
pentagon:5 lines of symmetry
Answer:
Step-by-step explanation:
We want to simplify;
We expand the bracket to obtain;
We now group the like terms to obtain;
We now simplify to get;
The correct answer is C
Step-by-step explanation:
you could count the squares around the shape or you could do it by points
For example point M is (2,3)
L is (6,3)
We want to find the length of this side so we subtract the x values
6 - 2 = 4 units
that gives use the length of that leg and since a rectangle is symmetrical, you can just measure 2 sides
<u>Answer
</u>
Option B) 7 is the correct answer
FD = 7cm
<u>Explanation
</u>
Here triangle AEC. D is the midpoint of EC and F is the midpoint of EA
So D and F be the midpoint of triangle AEC.
FD be the midpoint joining line.
We know that if any triangle, line joining the midpoint of two sides is the half of the third side.
Here the third side is 14cm, then FD = 14/2 = 7cm
So option B) is the correct answer.
Step-by-step explanation:
V = s^3 , so to find each side we need to find the cube root of 27
cube root of 27 = 3
therefore each edge is 3meters long
