Answer:
a(a+3) are the terms which can be cancelled.
Step-by-step explanation:
In this question if we factorize both the expressions then we can get the common factors which can be cancelled.
So first we factorize a²+3a = a( a+3 )
Now the second expression 
⇒
⇒
⇒
⇒
Now it is clear to us that factors a(a+3) are the common factors that can be cancelled.
Answer:
It will cost: £28.28
Step-by-step explanation:
Area of sphere = 4 x π x r2
Area of Circle = 4 x π x 3^2 = 113.097 (radius is half of diameter)

Answer:
3.5 m/hr
Step-by-step explanation:
2 + c = 5 -c c = speed of current
2 c = 3 c = current speed = 1.5 m/hr
your speed = 5 - 1.5 (or 2 + 1.5) = 3.5 m/hr
If I understood correctly, I believe this is the answer.
