Answer:
r = 10.5
Step-by-step explanation:
using the Pythagorean theorem:
(7 + r)² = 14² + r²
49 + 14r + r² = 196 + r²
subtract r² from both sides of the equation:
14r + 49 = 196
subtract 49 from both sides:
14r = 147
divide both sides by 14:
r = 10.5
Answer:
{8, 9, 10}
Step-by-step explanation:
Let's substitute each of the values to see if it makes sense.
8 + 7 < 18; 15 < 18
9 + 7 < 18; 16 < 18
10 + 7 < 18; 17 < 18
11 + 7 < 18; 18 = 18
Therefore, the answer is {8, 9, 10}.
Hope this helps!
Answer: Robert is correct, irrational numbers are part of real numbers.
Explanation:
In mathematics, numbers are classified into different groups or seats. In the case of real numbers, these are a broad category that includes all numbers that can be represented on a line. Moreover, this category includes smaller categories such as rational numbers, for example, 15, 2.4 or 6/2 that can be represented as fractions, as well as, irrational numbers such as that cannot be fractions. In this context, Jenny is incorrect and Robert is correct because irrational numbers are also real numbers.
