Notice that half of the coefficient of x is (1/2)(-4), or -2.
Then x^2 - 4x becomes
x^2 - 4x + 4 - 4 = 0, or (x -2)^2 = 4. Then x = -2 plus or minus 2, and the two roots are 0 and -4.
Thus, add 4 to both sides to obtain x^2 - 4x + 4 = 4.
Answer:
if the area of the base is 20 then the volume is 300 if it's 16 then it's 240 but if it's 25.6 then the volume is 384. I would give you a specific answer if the area of base was specified
Answer:
14 cm
Step-by-step explanation:
The first step is to find the area of the triangular base. The formula for the area of a triangle is 
. Now, you can divide the total volume by this to find the length. 1199.52/85.68=14. Hope this helps!
