Answer:
-15
Step-by-step explanation:
(fg)(1) = f(1)×g(1) = (5×1² -1 +1)×(-3·1) = (5)×(-3)
(fg)(1) = -15
2 - √3
tan45 = 1
tan60 = √3
2 tan 45 - tan 60
2(1) - √3
=> 2 - √3
y=-5/4x-8
2=-5/4(-8)+b
2=10+b
2-10=10-10b
-8=b
The unknown number is 12
2(x+26)=76
or,x+26=76÷2
or,x=38-26
Therefore,x=12.
3/4 is less < than 5/6
