Answer:
Oh.
Step-by-step explanation:
Answer:
4xy
Step-by-step explanation:
20x^2 y = 4*5 x^2 y = 2*2*5*x*x*y
16*x*y^2 = 4*4*x*y^2 = 2*2*2*2*x*y*y
what is common in both
2*2*x*y
4xy
<u>Examining the question:</u>
We are given the expression:

We know from Basic trigonometry that:


<u>Simplifying the expression:</u>
Replacing these values in the given expression, we get:

Since the denominator of both the values in the denominator is the same:

We know that
=
, using the same property:

and we are done!
Answer:
QR = 13.3
Step-by-step explanation:
We solve using Pythagoras Theorem
c² = a² + b²
RP² = PQ² + QR²
QR² = RP² - PQ²
QR = √RP² - PQ²
RP=15
PQ=7
QR = √15² - 7²
QR = √(176)
QR = 13.266499161
Approximately = 13.3
Therefore, the length of QR = 13.3
