Answer:
A = 4a² - 4ab + b²
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length ) , so
A = (2a - b)² ← expand using FOIL
= (2a)² - 2ab - 2ab + (- b)²
= 4a² - 4ab + b²
Answer:
This triangle is a obtuse traingle.
Step-by-step explanation:
First of all, it is impossible that this triangle is actute since the sides are different length.
Right is also not possible ( in this case ) because there are two pretty far sides.
30, 39
A obtuse triangle have a short side of 11 cm pointing top right and a side of 30 cm pointing directly to the right and the 39 cm side connecting the ends of the other sides.
\ Third side ( 39 cm , the one connecting
First side ( 11 cm ) \ the ends of side 1 and 2)
\______________
Second side ( 30 cm )
