<span>P = 2l + 2w
The given values fit the given formula</span>
The given values are 134
Let L = 5 - w
Solution:
P = 2l + 2w
134 = 2(5-w) + 2w 134 = 10-2w + 2w 134 – 10 = 4w 124 = 4w
31 = w
<span>26 = l</span>
Answer:
-2.4
Step-by-step explanation:
3(1)-5y=15
3-5y=15
-3 -3
-5y=12
÷-5 ÷-5
y=-2.4

Answer:
1
Step-by-step explanation:
sin x cos x(tan x+cot x)
=sin x cos x[(sin x)/(cos x)+(cos x)/(sin x)]
=sin x cos x [(sin²x+cos ²x)/(sin x cos x)]
=sin x cos x(1/(sin x cos x))
=1
