Answer:
c
Step-by-step explanation:
(x+25)(3+2x)-(x+4)(x+1)
=(3x+2x²+75+50x)-(x²+4x+x+4)
=(2x²+53x+75)-(x²+5x+4)
=2x²+53x+75-x²-5x-4
=x²+48x+71

And so on...
Answer:
200.96
Step-by-step explanation:
pi*r^2
The x-intercept also known as the root of a quadratic can be found by solving the equation with respect to x.
III is the most useful for finding the roots
you would simply equate each term to
So y= x + 6 AND y= x - 8
0= x + 6 0= x - 8
x= -6 x= 8
: . x-intercepts are x= -6 & x= 8
