Answer:
x=4
x=17.9
Step-by-step explanation:
For the first diagram.
cos(45°)=x/4√2
x=4√2cos(45°)
x=4
For the second diagram
tan(38°)=14/x
0.781=14/x
x=14/0.781=17.9
Independent variable: games played
Dependent variable: cost
The function can be factorised to (x+2)(x-1)^3 so the answer is true. x = 1 has a multiplicity of 3.
The LCM of 20 and 52 is 260
