Answer:
34 hundredhs
Step-by-step explanation:
27 plus 7= 34
Hey there,
The question is to find the product of the two factors (2p + q)(-3q - 6p + 1).
Now we just multiply across:
- -6pq - 12p² + 2p -3q²- 6pq + q
Now we combine like terms:
So the result would be -12p² - 3q² + 2p + q.
Hope I helped,

Answer:
60 minutes for the larger hose to fill the swimming pool by itself
Step-by-step explanation:
It is given that,
Working together, it takes two different sized hoses 20 minutes to fill a small swimming pool.
takes 30 minutes for the larger hose to fill the swimming pool by itself
Let x be the efficiency to fill the swimming pool by larger hose
and y be the efficiency to fill the swimming pool by larger hose
<u>To find LCM of 20 and 30</u>
LCM (20, 30) = 60
<u>To find the efficiency </u>
Let x be the efficiency to fill the swimming pool by larger hose
and y be the efficiency to fill the swimming pool by larger hose
x = 60/30 =2
x + y = 60 /20 = 3
Therefore efficiency of y = (x + y) - x =3 - 2 = 1
so, time taken to fill the swimming pool by small hose = 60/1 = 60 minutes
