630 cherries
You can setup a ratio using
and solve for x by multiplying 210*9 and dividing by 3 to get 630 cherries.
Lets put the problem all together first
1) p^2+mn
2^2+0(-1)
Now we start
2x2=4
0x-1=0
4+0=4
Your answer should be 4:)
2) m+np^2
0+-1(2)^2
2x2=4
-1x4=-4
0+-4=-4
Your answer should be -4:)
Volume of a box is equal to l*w*h
1242=l*6*12
1242=l*72
l=17.25
Final answer: 17.25 inches
Well I'm still trying to solve the first question so I'll tell you the other answers
the answer for the second question is :

and for the third question :
Hey there!
2/3 *30/1= 30/3= 10 and 3/3=1 so 2/1*10/1= 20
So the product is 20
