Answer:11.5cm, 23cm, 34.5 cm, 69cm
Step-by-step explanation:
1+2+3+6=12
138/12=11.5
First side=11.5cm
Second side=11.5x2=23cm
Third side=11.5x3=34.5cm
Fourth side=11.5x6=69cm
<span>The correct option is: A. f(x) = 4sin(x − π/2), because:
</span>
1. When you evaluate x=π/2 in the function f(x) = 4sin(x − π/<span>2), you obtain:
</span>
f(π/2) = 4sin(π/2− π/2)
f(π/2) = 4sin(0)
f(π/2) = 4(0)
f(π/2) = 0 (As you can see in the graphic)
2. If you evaluate x=π in the same function, then you have:
f(π) = 4sin(π− π/2)
f(π) = 4sin(π/2)
f(π) = 4 (As it is shown in the graphic)
<em> 9(x + 2)</em>
- <em>Step-by-step explanation:</em>
<em>Hi ! </em>
<em>6(x+4)+3(x−2) =</em>
<em>= 6x + 24 + 3x - 6</em>
<em>= 6x + 3x + 24 - 6</em>
<em>= 9x + 18</em>
<em>= 9(x + 2)</em>
<em>Good luck !</em>
