Answer:
x + 6
Step-by-step explanation:
(f ÷ g)(x)
=
factorise the numerator
=
← cancel the factor (x + 3) on numerator/ denominator
= x + 6
You have to simplify the 1/5 first.
Then simplify the square root of 1 to equal 1
Then rationalize the denominator
Then simplify
Answer:
The one on the right
Step-by-step explanation:
The height on the right one matches the height on the net, unlike the left one
Cos Z = 32/40 => Z= cos-¹(32/40) =>
sin Z = sin (cos-¹(32/40)) = 3/5
An estimate helps you place the decimal point because when you place 3.7 and 5.1 to multiply you have to count how many spaces of numbers there are. So the answer is 18.87.
