Answer:
A
Step-by-step explanation:
We have the expression:

And we want to find its sign given that a>0 and b<0.
Notice that the expression is already negative since we have -4.
a>0 means that a is positive. Therefore, we can ignore it since it won’t do anything.
b<0 means that b is negative. Therefore, we will have two negatives being multiplied together. Hence, this will make a positive.
Therefore, the sign of our expression will be positive.
We can see this with an example. Let a=1 (1>0) and let b=-1 (-1<0). Then:

So, the sign is positive.
Hence, the answer is A.
So than given that the diameter of a circle is 28 inches so from this result the radius is d/2 = 28/2 = 14 inches
than the circumference of circle will be equal 2*3,14*14 = 6,28 *14 = 87,92 so rounded equal 88 in.
so this mean that choice c.) is right sure
hope this will help you
The best interpretation is that the sum of 2.1 and –1.2 times a number is greater than or equal to 8.
<h3>Inequality functions</h3>
Inequality are expressions not separated by an equal sign, Given the inequality;
2.1 + (-1.2x) ≥ 8
The sign ≥ means greater than or equal to
The expression 2.1 + (-1.2x) ≥ 8 can also be expressed as 2.1 - 1.2x ≥ 8
The best interpretation is that the sum of 2.1 and –1.2 times a number is greater than or equal to 8.
