If your still using number blocks then it is 20 ones but if its just addition or so it is just 20
Answer:
5,4,6,-7
Step-by-step explanation:
The y's are range

For the statement to be true, 'a' and 'b' must be equal
*First expand the binomial using FOIL, then set it equal to whats given "2abi".
Then you can find the relationship between a and b.
Find the equation of the inverse.

we have

step 1
Exchange the variables
x for y and y for x

step 2
Isolate the variable y

apply log both sides

step 3
Let

therefore
the inverse function is
