Answer:
14
Step-by-step explanation:
We can find the value of x using similarity ratio
(2x-7)/57 = (x+4)/51 cross multiply expressions
51×(2x-7) = 57×(x+4)
102x - 357 = 57x + 228
102x - 57x = 228 + 357
45x = 585 divide both sides with 45
x = 13
Answer: x=4
Steps: (I am assuming your question has a typo in it and by "c" you meant "x")
The rational expression equals zero
only when the numerator equals 0 (the denominator cannot ever be zero):
and that happens only for x=4
X=-2
In the expression, x^2+4/x, substitute x with -2.
Therefore, the expression will be: -2^2+4/-2
-2^2 is -4. -4+4=0.
0 divided by any number is 0. Therefore 0 divided by -2=0
0 is the final answer.
18 divided by 9 = 2
9 = four bunches so 2 x 4 bunches
= bunches
