The first and last term factor into (2x+7) since this is a perfect square trinomial the answer must be 28
A rational number is any number that can be written in a/b form (like a fraction). So it just can't be a repeating decimal like how pie goes on forever. So let's see. 8.05 could work. Since you could write that as 8.05 over 1 (8.05/1)
No, if we think about the lines of symmetry in a square we can see that
although all of the diagonals are lines of symmetry there are also two
that perpendicularly bisect the edges of the square, these are not
diagonals. Also If we consider a rectangle we can see that the diagonals
of a rectangle are not lines of symmetry.
Answer:
60 cm²
Step-by-step explanation:
The side of the square is 8 cm, so the perimeter is:
P = 4s
P = 4 (8 cm)
P = 32 cm
The perimeter of the rectangle is:
P = 2w + 2h
32 cm = 2 (10 cm) + 2h
32 cm = 20 cm + 2h
12 cm = 2h
h = 6 cm
So the area of the rectangle is:
A = wh
A = (10 cm) (6 cm)
A = 60 cm²
