Step-by-step explanation:
Given prism has:
Length = 5 in, width = 4 in & height = 6 in
Surface area of prism

Answer:
f(x) = + cosx or - cosx
Step-by-step explanation:
(2+tan^2x/sec^2x) -1 =(f(x))^2
=(( 1 + sec^2x)/sec^2x) -1
= 1 / sec^2x + 1 - 1
= 1 / sec^2x
= cos^2x
(f(x))^2 = cos^2x
f(x) = + cosx or - cosx
It’s first 3 letters a,b, and c
-(-z + 3) equals z - 3
5 = z - 3
z = 8
