8+7+5= 20. The only color that is not red or blue is yellow. There are 8 yellows out of 20 cubes. The probability of selecting a cube at random that will not be blue or red is 8/20
Answer:
x=1 ,x= -5
Step-by-step explanation:
x+2x2-4=-7x+6
2x2+x+7x-4-6=0
2x2+8x-10=0
divide through out by 2 to reduce the equation
x2+4x-5=0
by using formula method
x=[-b+\-√b2-4ac]/2a. a=1, b=4 c=-5
x=[-4+\-√4^2-4*1*-5]/2*1
x=[-4+\-√16+20]/2
x=[-4+\-√36]/2
x=[-4+\-6]/2
x=(-4+6)/2 ,x=(-4-6)/2
x=2/2 , x=-10/2
x=1 , x=-5
-2(-3)^2-3(-3)+1=
6^2+9+1=
36+9+1=
46
