2 x length + 2 x width = perimeter.

2(2s-5) + 2(4s-13) = 108

Simplify:

4s-10 + 8s-26 = 108

Combine like terms:

12s - 36 = 108

Add 36 to both sides:

12s = 144

Divide both sides by 12:

s = 144/12

s = 12

Now replace s with 12 in each equation:

2(12) - 5 = 24-5 = 19

4(12) - 13 = 48-13 = 35

The answer is d. 35,35, 19,19

If tanx=-4/3 and x is in quadrant 2 then cos2x=?<br> A. 7/25<br> b. -3/5<br> c. -7/25<br> d. 3/5
sweet-ann [11.9K]

= (1 - tan^2 (x)) / (1 + tan^2 (x))  

= (1 - (-4/3)^2) / (1 + (-4/3)^2)  

= (1 - (16/9)) / (1 + (16/9))  

= (9 - 16) / (9 + 16) [By multiplying numerator and denominator with 9]  

= (-7) / (25)  

= -7/25
