=<span>12(a + b) + 4(2a + b) − 6(a + 3b)
=12a + 12b + 8a + 4b - 6a - 18b

Now, Try to put every a's together & every b's together,
= (12a+8a-6a) + (12b+4b-18b)
= 14a - 2b

In short, Your Answer would be 14a - 2b

You need two sides so you can rewrite it as:
2x = 70-(14+32)
2x = 24
x = 24/2
x = 12

The height is 12in.

How do i prove 2sec^2x-2sec^2xsin^2-sin^2x-cos^2x=1

kramer

$2\sec^2x-2\sec^2x\sin^2x-\sin^2x-\cos^2x=2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)$

Since $\sin^2x+\cos^2x=1$ , you have

$2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)=2\sec^2x\cos^2x-1$

and since $\sec x=\dfrac1{\cos x}$ , you end up with $2-1=1$ .
