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
for a put 6 and b put -9
Explain: 6(-9) is equal to -54
and 6- -9 is 15 because the minus turns into a plus sign and the negative number turns into a positive number.
Answer:
Step-by-step explanation:
ok so first u have to multiply 9x5 which is 45 and put it under the 5
then u multiply 3x5 which is 15 and u put it under the 5 next to the 3
u do the samething over and over, is just basically time tables
