Answer:

F 8.4

Step-by-step explanation:

4 [ 4.5 - 2(1.2)]

First, multipy 2 and 1.2

2 x 1.2 = 2.4

Then subtract 2.4 from 4.5

4.5 - 2.4 = 2.1

Last, multiply 2.1 from 4

4 x 2.1 = 8.4

The answer is: True.

A counterexample is a way that we can prove that something is not true about a mathematical equation or expression, it's also considered as an exception to a rule.

So:

$sec^{2}x-1=\frac{cosx}{cscx}\\\\tg^{2}x=\frac{cosx}{\frac{1}{sinx}}\\\\\frac{1-cos2x}{1+cos2x}=cosxsinx$

Then, evaluating we have:

$\frac{1-cos(2*45)}{1+cos(2*45)}=cos(45)*sin(45)\\\\\frac{1-0}{1+0}=\frac{\sqrt{2} }{2}*\frac{\sqrt{2}}{2}\\\\1=\frac{(\sqrt{2})^{2} }{4}\\\\1=\frac{2}{4}\\\\1=\frac{1}{2}$
