V = thr2 rearrange the formula to solve for h

h=-tr2-V

Step-by-step explanation:

V=thr2

V-h=tr2

-h=tr2-V

-tr2-V=h

therefore,

h=-tr2-V

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
