Answer:
percentage error = 12.28%
Step-by-step explanation:
5 x 0.14 = 0.7
5 x 1.14 = 5.7
as increase is not the same as error decrease.
We use the same numbers 12.28% = 0.1228.
5.7 x 0.1228 = 0.69996 = 12.28%
5.7 - 0.69996 = 5.00004 foot. As decrease.
And find it is correct.
His error therefore was 12.28% out.
As we work the first numbers 5.7 and can only x by a number to see 5ft
We take 5.7 x 0.1228 and find 0.69996 when taken from 5.7 ft. is unmistakably 5 foot. (5.00004) ft.

Answer:
A
Step-by-step explanation:
x^2 + x - 12
12 = 4*3,
We have -12 so 4 or 3 should be negative.
+ x , coefficient = +1 , so we have +4 - 3 = +1
(x+4)(x-3)
We can check:
(x+4)(x-3) = x^2 + 4x - 3x -12 = x^2 + x - 12
