Answer: GCF = 14
Step-by-step explanation:
The factors of all numbers:
14 - 2, 7, 14
28 - 2, 4, 7, 14, 28
42 - 2, 7, 14
As you can see, 14 is our GCF.
Answer:
A∪B = { The Real numbers }
Step-by-step explanation:
Given:
Let A = {the Rationals} and B = {the Irrationals}.
Find
A∪B.
Solution :
AUB means collection all the element of A and all the element of B.
element of A = Rational number and
element of B = Irrational number
Real number : All the including rational and irrational numbers are called as real number.
∴ A∪B = { The Real numbers }
Answer: 5
Step-by-step explanation:
use formula a^2 + b^2 = c^2
a^2 + 12^2 = 13^2
a^2 + 144 = 169
- 144 -144
a^2 = 25
sqrt sqrt
a = sqrt (25)
a = 5
