X² - 11x + 18
find factors of x² and 18 that will give you -11x
x² - 11x + 18
x -9
x -2
(x - 9)(x -2) is your answer
if you are finding the x, place each parenthesis equal to zero
x - 9 = 0
x - 9 (+9) = 0 (+9)
x = 9
x - 2 = 0
x - 2 (+2) = 0 (+2)
x = 2
x = 2, 9
hope this helps
Answer: 0
Step-by-step explanation: Good luck! :D
Yo yo what’s your name on the phone back on your internet please send it
Tan(15) = tan(45 - 30)
= [tan(45) - tan(30) ] / [ 1 + tan(30)tan(45)]
= (1 - 1/sqrt(3)) /(1 + 1/sqrt(3))
= (sqrt(3) - 1)/(sqrt(3) + 1)
= (sqrt(3) - 1)^2 /(3 - 1)
= 1/2 [3 + 1 - 2sqrt(3) ]
= (2 - sqrt(3) )
= 0.27 is your answer
Answer:
x = 63
y = 47
Step-by-step explanation:
