Hey there! :)
3 - (-2) = ??
Let's keep in mind that a negative times a negative is always a positive!
In addition, let's also remember that parenthesis mean multiplication - so that's how we know that we're multiplying!
So, since a negative times a negative equals a positive, then we know that this question is essentially just asking us what 3 + 2 is!
In case we aren't sure how to do this, let's look at our fingers! We start out with 3 fingers, and add 2 more fingers to it! So, 3 fingers to 2 fingers equals 5 fingers!
Therefore, our answer is 5.
3 -(-2) = 5

Step-by-step explanation:
The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)
<h3>What is the measure of the missing interior angle in a heptagon?</h3>
Heptagons are polygons with seven sides, seven vertices, seven <em>interior</em> angles and seven <em>central</em> angles. Herein we know the value of the sum of six interior angles and we need to know the measure of the seventh <em>interior</em> angle. We can determine the measure of the seven interior angles by using the following expression:
θ = (n - 2) · 180°, where n is the number of sides of the polygon. (1)
If we know that n = 7, then sum of the internal angles in the heptagon is:
θ = (7 - 2) · 180°
θ = 900°
And the measure of the final interior angle is found by subtraction:
θ₇ = 900° - 776°
θ₇ = 124°
The measure of the seventh <em>interior</em> angle of the heptagon is 124°. (Correct choice: C)

Hello! What we need to do first in this kind of problem is multiply the numbers at be beginning of those notations. In this case, those numbers are 6.3 and 8.4. 6.3 * 8.4 is 52.92. We'll come back to this number in a bit. Now, let's worry about the exponents. When it comes to simplifiying scientific notations by multiplying, we need to add the exponents together. In this case, those are 8 and -3. 8 + (-3) is 5. Going back to 52.92, that number is greater than 10, so this will not work in scientifc notation. A number beign multiplied by a power of 10 is supposed to be greater than or equal to 1, but less than 10. We can make that number become less than 10 by moving the decimal to the left once to get 5.292. That works. But we're not done, now we must add 1 into the exponent, which is 5. 5 + 1 is 6. We can now write this in scientific notation:
5.292 * 10^6
There's our answer! That would be 5,292,000 in standard form, because 10^6 is 1,000,000. The notation simplified is 5.292 * 10^6.
