Step-by-step explanation:
STEP 1
Equation at the end of step 1
(((x3) - 22x2) + x) - 4 = 0

Leasing a car is the better option if they only want to keep it for a certain amount of years. This is because with leasing you are only paying the depreciation of the car instead of the buying price. Also, it benefits people that can't pay the down payment for the car.

Find cos using trig identities:

Therefore

Sub in tan x = 3, (Note that x is in 3rd quadrant, cos x < 0)

Finally, sub into Half-angle formula:(Note x/2 is in 2nd quadrant, tan x<0)
Answer:
Answer: x will be equal to 5 and -8
Step-by-step explanation:

» Divide all equation through out by -2:

» Factorise the equation quadratically:

Daniel wants a triple quantity
We times everything by scale factor if 3
