False
because tan^2 45 = 1^2 = 1
and sec^2 x = 1/ cos^2 45 = (sqrt2)^2 = 2
so the sum = 3
Answer:
(x-2)(x+1)
Step-by-step explanation:
x²-x-2 can be factored into:
(x-2)(x+1)
Support me by selecting my answer as brainiest.
Let the initial population = P
increase in population = 35%
35% of P = 35/100 P = 0.35P
P + 0.35P = 91800
1.35P = 91800
P = 91800/1.35
P = 68,000
Previous population was 68,000
