Answer:
Step-by-step explanation:
cannot be factorised in the form (x+b)(x-b) unless one of the b's is zero, so I wonder if the expression is incomplete?
To factorise , take out the common factor 
:
Therefore, x = 0 and x = 4
- - - - - - - - -
factorised in the form (x+b)(x-b) would be 
but it is not usual to have a zero in a factorised form.
775 + 4.25 times the number 12
Answer:
40.4%
Step-by-step explanation:
Given data
Initial depth= 5feet
Final depth= 5-3.2+6.6= 8.4feet
Hence the percent change
% change= FInal-initial/final*100
% change= 8.4-5/8.4*100
% change= 3.4/8.4*100
% change= 0.404*100
% change=40.4%
Hence the percent change is 40.4%
