Start with

\dfrac{x}{2}+\dfrac{3}{2}

Multiply the whole equation by 2. Since 2 is positive, we don't need to switch the inequality sign:

x+3

Subtract 3 from both sides:

x

SHOW that (x + 3) and (x - 2) are factors of f(x) = x4 + 10x3 + 23x2 -<br> 34x - 120.
Anna35 [415]
If f(x) = 0 then it is a root

x + 3 = 0
x=-3
f(-3) = (-3)^4 + 10(-3)^3 + 23(-3)^2 - 34(-3) - 120 = 0

x - 2 = 0
x=2
f(2) = (2)^4 + 10(2)^3 + 23(2)^2 - 34(2) - 120 = 0

Hurry please find the values of x and y
MrRissso [65]
Answer:
Y=70
X= 20
You do first the adjacent angles 180-40 so 140 then u have that the triangle is isosceles so the bas angles are equal 180 -140 = 40
40 divided by 2 20 and 20 so x= 20
Then 90 -20 is 70
So 180 - (70+40)
180-110=70 so y= 70
Hope you understand
