Factor the 25 where they multiply to make 25 and add to make 10 so now it's (x+5)and (x+5) so x=-5 because x+5=0 solved
Answer:
see explanation
Step-by-step explanation:
Using the double angle identity for sine
sin2x = 2sinxcosx
Consider left side
cos20°cos40°cos80°
= (2sin20°cos20°)cos40°cos80°
= (2sin40°cos40°)cos80°
= (sin80°cos80° )
= (2sin80°cos80° )
= . sin160°
= . sin(180 - 20)°
= . sin20°
= = right side , thus proven
Answer:
6x-y-4=0 is the linear coordinates.

Answer:
Step-by-step explanation:
we know that
The roots of f(x) or the x-intercepts of f(x) are the values of x when the value of f(x) is equal to zero
In this problem
Observing the graph
The roots are and the multiplicity is
-1-------> multiplicity 1 (odd number)
+1 -----> multiplicity 2 (even number)
+3-------> multiplicity 1 (odd number)
