That's what I got. to rationalize the numerator you have to multiply by the conjugate, in this case (√3 + 9) / (√3 + 9), which is what it looks like you did.

The answer should and must be 37.5 . you get that by dividing 30/80 which equals to 0.375 . Hence the answer times 100 which gets you 37.5
Im not sure but i think its either 19.50$ or 20$
Answer: AC = 98
Step-by-step explanation:
A midpoint is a point on a line segment that divides it into <em>two equal parts</em>.
This means AB = BC
AB = 8x - 7
BC = 6x + 7
AB = BC
8x - 7 = 6x + 7
Solve this to find x
Add 7 to both sides
8x = 6x + 14
Subtract 6x from both sides
2x = 14
Divide both sides by 2
x = 7
Now AC = AB + BC
AC = AB + BC
AC = 8x - 7 + 6x + 7
AC = 14x
Substitute 7 for x
AC = 14(7)
AC = 98
Hope this helps!
let's recall the vertical line test, it's a function if when dropping a vertical line on the graph, it only touches it once on the way down.
