Answer:
x, x+2, x+4
(x+2)^2 - 4(x) = 6(x + 4) + 7
x^2 + 4x + 4 - 4x = 6x + 24 + 7
x^2 - 6x - 27 = 0
x = 9 (∨ x = -3)
The three numbers are
9, 11, 13
but it could be also
-3, -1, 1
Answer:
Hi use the attached formula to calculate the midpoints
Attached also is an example
Hope this helps
we are given the data of lengths 5 and 10 of an acute triangle and is asked to detemine the length of the third side. In this case, it cannot be 4 since the sum of 5 and 4 does not exceed the longest one. Sides 6 and 11 result to an obtuse triangle. Answer is B.5
I hope you understand this. Remember x alone stands for 1
