The improper fraction 5/2 can be converted to the mixed number 2 1/2
I would say D because, it makes sense the most, absolute values make the negatives positive, so the order that D goes in is correct.
Answer:
1.58
Step-by-step explanation:
The answer should be 1.58 because 12.64 divided by 8 is 1.58
We must know that the are of the triangle is given by definition by
A = (1/2) * (b) * (h)
where
b = base
h = height
Substituting the values
A = (1/2) * (x) * (1 + 6x)
A = (1/2) * (x + 6x ^ 2)
Since the area is 13 then
(1/2) * (x + 6x ^ 2) = 13
Clearing x we have
6x ^ 2 + x = 26
6x ^ 2 + x-26 = 0
(x-2) * (x + 13/6) = 0
As we look for the base of a triangle then x> 0
x = 2
answer
the base is x = 2
6x ^ 2 + x = 26
