ANSWER: 11, 12, 13
3 consecutive integers:
"Sum" means Add
Combine like-terms
Solve for X
Subtract 3 from both sides
Divide by 3 on both sides
11 + 1 = 12
11 + 2 = 13
Answer:
B
Step-by-step explanation:
yes, we need two numbers that multiplied with each other results in -48.
that means already that one of them has to be positive and the other negative.
that gives us (with all +/- alternating sign combinations)
2 and 24
3 and 16
4 and 12
6 and 8
to pick from there we see that the "middle" term is -2x.
that means that the absolute value of the negative number has to be 2 more than the positive number (so that when adding the intermediate multiplication terms we end up with -2x).
the only choice is therefore 6 and -8.
and that makes B the right answer.
In the case of a circle, the formula for area, A, is A = pi * r^2, where r is the circle's radius. Since we know that a semicircle is half of a circle, we can simply divide that equation by two to calculate the area of a semicircle. So, the formula for the area of a semicircle is A = pi * r^2/2
5 and 1/4 is on 5 inches and 3 cm
The answer would be x=0, 2i, -2i
