Answer:
15.) 9.5%, 5/9, 0.95, 99%
16.) 0.35, 3/8, 38%, 50%
17.) 44.5%, 0.45, 54%, 4/5
18.) 0.3, 3%, 20%, 1/3
Step-by-step explanation:
x= 35
Cos x = Sin( 20+x)
Sin ( 90 – x) = Sin(20+x)
90 – x = 20+x
2x = 70
x = 35
x^2 + 10x - 9
(1+2)3 = 1(x(x+10))
Hello,
8 - 2ab
8 - ( 2 * 2 * 3 ) = 8 - 12 = -4
Bye :)
