Answer:
Step-by-step explanation:
x²+3x+2=0
x²+x+2x+2=0
x(x+1)+2(x+1)=0
(x+1)(x+2)=0
x=-1,x=-2
so B
Answer:
3 1/3
Step-by-step explanation:
10+z=z+z+z+z
10+z=4z
10=3z

<h3>
Answer: 139.5</h3>
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(55) = 80/x
x*cos(55) = 80
x = 80/cos(55)
x = 139.4757 approximately
x = 139.5
