Area=length*width
(32+48)=(16)*(width)
80=(16)(width)
width=(80/16)
5=width
We are given :
Step 1: factor the part inside square root
The function given inside square root is of quadratic form.
So let us try to factorise it using AC method.
Here A*C = 4*25 = 100
so we have to find factors of 100 that add up to give -20.
the two factors are -10 and -10.
Rewriting the function :
=
=
=
Step 2:
Now we take square root of the factorised form
=
Answer : (2x-5)
Answer:
B. point B
because -16/6 = - 2.67 here we can see the point B is in that place so.
