Answer:
The sum of two negative integers is always negative.
Step-by-step explanation:
For example, add -1+-1 which =-2, which are the smallest neggative numbers possible.-100+-100=-200, and -4+-4=-8, so you see that the sum of two negative integers should always be negative.
V = 1/3 × (pie) × radius^2 × height of cone
My answer is C
because
x-12=-3
x=-3+12
x=9
