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.

I’m pretty sure it would be the third option, 162
X=-53x+378, if you need explanation used ask me.
Hello,
Let's a and b the 2 angles.
a+b=180 (1)
a=b/3+8 ==> 3a-b=24 (2)
(1)+(2)==>4a=204==>a=51(°) and b=180-51=129(°)
Proof:
129/3+8=43+8=51
129+51=180
