The answer to the first one is A, the second one is 3.58333
Answer: 1
Step-by-step explanation:
Gcf of 3 : 1 * 3
Gcf of 12184 : 1 * 12184
2 * 6092
4 * 3046
8 * 1523 .......
Gcf of 1545: 1 * 1545
3 * 515
5 * 309
All the the numbers do not have any common number except 1 so therefore 1 is the only common number which makes It the GCF in all three numbers.
4 and 5 both go into 20
1/4 equals 5/20
2/5 equals 8/20
So 2 and 5/20 + 1 and 8/20 is
3 and 13/20
Answer:
The parallelogram is not rectangle because the sides of the parallelogram do not meet at right angles.
Step-by-step explanation:
Given the parallelogram with sides 20 and 21 units with diagonal length 28 units.
we have to tell it is a rectangle or not.
The given parallelogram is rectangle if the angle at vertices are of 90° i.e the two triangle formed must be right angles i.e it must satisfy Pythagoras theorem
=
+![21^{2}](https://tex.z-dn.net/?f=21%5E%7B2%7D)
784=400+441=881
Not verified
∴ The sides of the parallelogram do not meet at right angles.
Hence, the parallelogram is not rectangle because the sides of the parallelogram do not meet at right angles.
Hope it helps

Answer:
20x^2 + 47x + 24
Step-by-step explanation:
The area of a rectangle is LENGTH * WIDTH. From the diagram, we see that LENGTH = 4x + 3 and WIDTH = 8 + 5x. Therefore the area is:
A = LENGTH*WIDTH
= (4x+3)(5x+8)
= 20x^2 + 32x + 15x + 24
= 20x^2 + 47x + 24
