Answer:
area = 8a^2 +4ab
Step-by-step explanation:
Area = (4a)(2a + b)
= 8a^2 +4ab
Answer:
pi/2
Step-by-step explanation:
Arccos(tan(0))
Arccos( 0) since tan(0)=0
Arccos(0)=pi/2 since cos(pi/2)=0 and the restricted domain of cosine is [0,pi].
Answer:
A
Step-by-step explanation:
Vertex appear to be at (5,115)
A) h = -b/2a
= -(20)/2(-2) = 5
k = -2(5²) + 20(5) + 60 = 110
Answer:
100units^2
Step-by-step explanation:
Using pythagoras theorem, it states that 36+64= area of the unknown
