For a width of 25, the length will also be 25, so the area is 25² = ...
625.
_____
The rule is
area = width×(50 -width)
Domain is x’s and range is y’s.
For a, the domain is -2<=x<1
For a, the range is 1<=y<2
For b, the domain is 1<=x<=2
For b, the range is -2<=y<=2
(The <= is the ones with a line under, meaning equal to, if that makes sense. So write with a line under rather than equal sign)
Hope this helps!
(c/ b * 0) is just (c/0) and you cannot divide by 0
4280 because 75+5+4200= 4280
