Answer:
D: 65 km²
Step-by-step explanation:
The formula for area of a hexagon when given the base is
A = (3/2)(√3)b² where b is the length of the base
Here, b is given as 5, plug that in and simplify
A = (3/2)(√3)(5²)
A = (3/2)(√3)(25)
A = (75√3)/2
A ≈ 64.95 ≈ 65
Answer: A. 17 - 17 = 0
Step-by-step explanation:
A variable is a number
Answer:
11
Step-by-step explanation:
f(x) = 3x^2
– 4x – 9
Let x = -2
f(-2) = 3 (-2)^2 -4(-2) -9
=3(4) +8 -9
=12 +8 -9
20-9
