Answer:
p = 11.2
Step-by-step explanation:
2.6(5.5p - 12.4) = 127.92
14.3p - 32.24 = 127.92
Add 32.24 to both sides
14.3p = 127.92 + 32.24
14.3p = 160.16
Divide both sides by 14.3 (the coefficient of p)
p = 11.2
The answer must be - cospi/2 which is not available in the option
4x^2-5x=-1
4x^2-5x+1=0
4x+2.24x=1
6.24x=1
