hi
a ( b +c) = a*b +a*c
here a = -3
b = -4x
c = +5
so :
-3 ( -4x +5) = -3*-4x + -3* 5
= -12x + (-15)
= -12x -15
as I cannot add -12x and -15 ( they are two differents sort of figures )
so it's done
Answer:
The correct option is C
Step-by-step explanation:
Alternate exterior angles have the same measure .the correct option is C
W is 5 units
w=(P-2l)/2
w=(30-2(10))/2
w=(30-20)/2
w=(10)/2
w=10/2
w=5
