I would say option A because as there’s more liquid that’s inside the sponge now, it weighs more than it has before. The sponges volume does increase , but not as much
Eighteen divided by three is an easy division question in. The answer to 18 divided by 3<span> is equal to 6.With counters you should count out 18 then take out 3 then another 3,then another 3,then another three,then another 3, then another 3.You should have took out 6 groups of 3.</span>
First problem: I believe YW: 34
ZX: 17
VX: 34. I have a pic attached but it probably doesn’t make much sense :)

Why?
The first thing we need to do is find the area of the triangle, we can to that by subtracting the area of ABCD from ACBE, then, we can use the formulas to calculate the area for both triangle and rectangle to find "f" and "g".
Calculating we have:

Now, we can calculate "f" by using the formula to calculate the area of the triangle:

Now, finding "g" by using the formula to calculate the area of the rectangle, we have:

Hence, we have that:

Have a nice day!
