Even answering one is huge for me please help.

I am not sure if it's correct but for 20) I think it is 150

Step-by-step explanation:

First to find the area of the triangle is base times height divided by 2. So 12×8=96 then 96÷2=48

For the rectangle is 12×7=84

For the little square is 6×3=18

If you add them all together it would be 150

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
