Step-by-step explanation:
if you reflected -2 -4 it would be 2 -4
Answer:
When you multiply an odd number of negatives you get a negative result. When you multiply an even number of negatives you get a positive result.
First, multiply normally.
25x10x5
1100
Then determine whether the sign is positive or negative. Since there is an odd number of negatives, the sign is negative.
So, the answer is -1100.

Answer:
10 cm
Step-by-step explanation:
The larger polygon is also a regular 6-sided polygon, so each side is 1/6 of the perimeter length:
(60 cm)/6 = 10 cm . . . length of a side

Answer:</h3>
818.4 in²
<h3>
Step-by-step explanation:</h3>
The area of a circular sector is given by ...
... A = (1/2)r²·θ . . . . . θ in radians
The area of the isosceles triangle with apex angle 150° is given by ...
... A = (1/2)r²·sin(θ)
Then the area of the shaded segment is ...
... A = (1/2)r²·(θ - sin(θ))
... A = (1/2)·(27.8 in)²(5π/6 -sin(5π/6)) ≈ 818.4 in²
_____
If you (erroneously) use 3.14 for π, you get 817.9 in². Some answer keys expect you to use that value, even though it does not have sufficient accuracy for this problem.
