Answer:
20
Step-by-step explanation:
One pattern is that we are adding one row and one column for each step.
The first step has 1 row and 2 columns,
the second one has 2 rows and 3 columns,
and the third has 3 rows and 4 columns.
Thus, it would make sense for the fourth step to have 4 rows and 5 columns. This makes a rectangle with a length and a width, with the area of the rectangle being length * width. 4 * 5 = 20 as our number of dots
Answer:
(-∞, ∞).
Step-by-step explanation:
This function can have any real value.
Range = (-∞, ∞).
If you’re looking for equivalent expressions then there’s this:
5(2+3) = 5*5
5(2+3) = 10+15
If you’re looking for the answers, it’s 25. This is because 5*2=10 and 5*3=15. 10+15 is 25. Or you could add 3 and 2 (which is 5). Then 5*5= 25.
Hope this helped :)
