Answer:
the answers are 12.5, 5, 2, 0.8 and 0.32
Step-by-step explanation:
2(0.4)^-2
=2(6.25)
= 12.5
2(0.4)^-1
= 2(2.5)
=5
2(0.4)^0
=2(1)
=2
2(0.4)^1
=2(0.4)
=0.8
2(0.4)^2
=2(0.16)
=0.32
Its called an Scalene triangle
Answer:
A and C the other two are just stand alone numbers. so the answers are A and C
Translation right down c=
(-2)^4 = (-2) (-2) (-2) (-2) = 16
so n = 16
