Answer:
375
Step-by-step explanation:
2400=2^5*3*5^2
2400>2025
2400-2025=375
The right answer for the question that is being asked and shown above is that:
1)linear equation (specific) => A)2x + 3y = 8
2)graph of system of linear equations with no solution => E)parallel lines
3)slope of a vertical line => D)no slope
4)graph of linear inequality => <span>F)half-plane </span>
5)slope of a horizontal line => <span>C)0 </span>
6)system of linear equations => B)2x + y = 7 and 3x - 4y = 8
We apply the Law of Sines
<span>a/sin A</span> = <span>b/sin B</span> = <span>c/<span>sin C</span></span>
We have that b = 12, B = 15 degrees
<span><span>C = 90 degrees</span></span>
....> c/sin(90) = 12/sin(15)..............> c = 12/0.258 = 46.3644
If we had two of these they'd fit together to form a nice 5 by 7 by 8 rectangular prism, just like the last one.
So our area is (5)(7)(8)/2 = 35(4) = 140
Choice B
The answer is -17
The negative 7 and positive 7 add up to 0. They are opposites which cancel out. Think of it like being 7 dollars in debt (negative 7) and that debt is fully canceled out by the positive amount of money (positive 7). Put another way, the negative 7 means you go down 7 while the positive 7 means you go up 7.
After the first two terms cancel to 0, the -17 is the only thing left. Adding 0 to any number keeps that number the same.
