According to the question of the statement, we can conclude that
PQ = 2B
QR = 2B
PR = base = B
Perimeter = P = 105
P = PQ + QR + PR
105 = 2B + 2B + B
B = 21
<h2>PQ = 2B = 42</h2><h2>QR = 2B = 42</h2>
Answer:
The given Expression is sometimes true.
Step-by-step explanation:
from the question,
The given expression by Cary is .
So, solving the expression we get
⇒
Let is an integer.
Whenever,
(a) {
}
The given Expression always gives negative value.
(b) {
}
The given Expression always gives positive value.
