Answer will be D.
!! Hope It Helps !!
Easy
set to zero
those are the roots or xintersepts
(x+1)(x+4)(x-7)=0
x+1=0
x=-1
x+4=0
x=-4
x-7=0
x=7
xints are (-4,0) (-1,0) (7,0)
360 degrees in a circle
360 degrees minus 90 degrees (the right angle of the square) = 270 degrees
270 degrees divided by 2 = 135 degrees
f = 135 degrees
12n = 3-5n-1 or n =3-5n-1???
Answer:
x = -7
Step-by-step explanation:
2x+3 = x-4
2x-x = -4-3
x = -7
