X^2-2x -3 =0
a =1 b =-2 and c = -3
x = - (-2) +/- sqrt (-2)^2 - 4(1)(-3)
--------------------------------------
2(1)
x = + 2 +/- sqrt [(4) - 4(-3)]
-------------------------------

x = +2 +/- sqrt [4 + 12]

x = +2 +/- sqrt[16]

x = 6/2 or -2/2
x = 3 or x = -1
its 30 because if you add the numbers together then you get 90, then you do 180-90 and get 90, divide 90 by 3 and get 30
Answer:
h<-8/3
Step-by-step explanation:
collect like terms
-10h+7h>9-1
3h>8
divide both sides of the inequality by -3 and flip the inequality sign
h<-8/3
A. f(b) = 3+b
b. f(x) = (x+3)²
c. f(x) = (x+3)/(12-x)
d. f(x) = x⁵-4x+6
e. f(x) = -45
f. f(x) = x
