Yes, It would be reasonable since thats about the weight of a skateboard.
However, the average skateboard is closer to 6 pounds. So, the skateboard in the question is very possible- but it would be really low quality.
However- given that you are in middle school- I would say yes, it is reasonable.
Any kind of Triangle must have 180 degree of angle in total if it is not, then it is not a Triangle.
In short, Your Answer would be Zero
Hope this helps!
Answer:
x = 4
Solution:
Combine like terms and simplify.
Answer:
(-4, 3] U (3, 8]
Step-by-step explanation:
The first lines range is (-4,3]
(the round bracket is because the -4 not included ( clear circle) and the square on because the 3 is included in the range ( the filled circle))
second line - range is (3, 8]
So its (-4, 3] U (3, 8]
All of the equations contain -4 in their range.
A) -4 = sqrt(x) - 5
1 = sqrt(x)
x = 1; valid
B) -4 = sqrt(x) + 5
-9 = sqrt(x)
x = 81; valid
C) -4 = sqrt(x + 5)
16 = x + 5
x = 11; valid
D) -4 = sqrt(x - 5)
16 = x - 5
x = 21
I believe the equations contain square instead of square root, in which case the answer would be A because no other could have a negative range.
