EF=9 cm. Both triangles are the same.
800+16x=720+21x
80+16x=21x
80=5x
X=16
So 16 hours :)
Answer: y=-5x-8
Step-by-step explanation:
2x^2-4x+2=x+2. 2x^2-4x+2-x-2=0. 2x^2<span>-3x-0=0. use quadratic formula = </span>(-b+- squareroot(b^2-4ac))/2a. so ur a=2<span> b=-3 c=0. hope this helped</span>
Answer:
X would be x < 9
Step-by-step explanation:
You would do this equation like any other equation, but with the equal sign being greater or less than. So you would add 4 on both sides to get x < 9
