In geometry, a line segment<span> is a part of a </span>line<span> that is bounded by two distinct end points, and contains every point on the </span>line<span> between its endpoints. A closed </span>line segment<span> includes both endpoints, while an open </span>line segment<span> excludes both endpoints; a half-open </span>line segment<span> includes exactly one of the endpoints.</span>
The answer would be A because if you combine all the like terms you will get A as a result.
-2x^2+8x-9+4x+7x^2+2
-2x^2+7x^2 combine both of these and it will get you 5x^2
And then you would do 8x+4x which would be 12x and lastly you would -9+2 which would be -7 so the answer is A.
Hope this helps!!
Answer:
-1050
Step-by-step explanation:
-650+(-400)=-1050
We use negatives to show it is below sea level
Answer:
b/38,304
Step-by-step explanation:
when you multiple 252 times 157 you will get 38,304.

Actually Welcome to the Concept of the areas.
Since we know that, radius = diameter /2
here, => d = 2r ,
hence we use the formula as,
A = πr^2 ,
here option d.) is correct.
