i think you have to multiply those. thats it
First you can combine 30tu^2 and 12tu^2 because they both have tu^2
So it would be 42tu^2 + 24tu
The answer is
6tu ( 7tu + 4 )
It is 15 meters long on each side.
You find the square root of 225 which is 15, because when you multiply 15 by 15 you get 225.
We have that
1 1/2 acres-------------> 1.5 acres
one hour----------------> 60 minutes
Step 1
I proceed to make a rule of three
<span>if Jami can now mow 1/6 acre -----------------------> in 8 minutes
1.5 acres----------------------------------------------> X
X=1.5*8/(1/6)=72 minutes
72 minutes > 60 minutes
therefore
</span><span>Jami can not mow 1 1/2 acres in an hour
</span><span>The time required by jami to mow 1 1/2 acres is 72 minutes</span><span>
</span>

Lol I think I've explained this enough times now so you know the process
