2(n+4) + 6 = (1/2)(3-n)
Then 2n + 8 + 6 = 3/2 - n/2
and 2n + 14 = 3/2 - n/2
(5/2)n = 3/2 - 28/2 = -25/2
-25/2
n = -------------- = -5 (answer)
5/2

It did not say if if it was a acute triangle or a obtuse triangle
Answer:
7/60 hour or 7 minutes b) 8 or 8 4/7 depending if you consider a fraction of a task is yes or no
Step-by-step explanation:
The formula for area of a triangle is A = bh/2, where b is the base length and h is the height of the triangle. For this triangle, the base is twice as big as the height; the base and height are represented as follows.
Height: h
Base: 2h
The area of the triangle is 64. Plug all values and expressions accordingly into the formula for area and solve algebraically for h.
A = bh/2
64 = 2h(h)/2
64 = 2h²/2
64 = h²
8 = h
b = 2h
b = 2(8)
b = 16
Answer:
The height of the triangle is 8 units and the base is 16 units.
13 of 25 would mean that the percent of error is 86%
