You can draw a line to make a square and a rectangle to help find the area. The other method would be to form 2 squares and 1 rectangle.
This is probably wrong but I hope it helps!
Factor the polynomial:
4u² – 20u + 25
Rewrite – 20u as – 10u – 10u, and then factor it by grouping:
= 4u² – 10u – 10u + 25
= 2u * (2u – 5) – 5 * (2u – 5)
= (2u – 5) * (2u – 5)
= (2u – 5)² <––– this is the answer.
I hope this helps. =)
The formula is y=mx + b, or rearranged would be m= y/x -b/x.
I am quite sure that it is B: Temperature
