Answer:
C 1
Step-by-step explanation:
x-1/x-2 - x^2+4x-4/(x-2)(x+6)
rewrite: (x-1)(x+6)-(x^2 + 4x - 4)/(x-2)(x+6)
expand x^2+6x-x-6-x^2-4x+4/(x-2)(x+6)
collect like terms (x^2-x^2)+(6x-x-4x)+(-6+4)/(x-2)(x+6)
simplify x-2/(x-2)(x+6)
cancel x-2 and get 1/x+6
but that is the only answer I can get from this, so I believe many one, just because of the numerator
Answer:
81 cm is 0.81 metre
12 tonne is 12000 kg
Volume of a cube is a^3
V=0.531441
D=M/V
=12000/0.531441
Density is 22580.11708 kg per m cube

Answer:
Step-by-step explanation:
In standard form this could be rewritten as | b - 0 | > 6, which in words, says,
"b is greater than 6 units away from 0 on a number line". If b is greater than 6 units away, both positive 6 and negative 6 are 6 units away from 0. Because the values we need are greater than 6 units away from 0, we are starting at both 6 and -6 and moving away from 0.
The "greater than" symbol indicates that this is a disjunction so the word "or" is used as opposed to in a conjunction where the word "and" is used.
Therefore, our solutions are
b < -6 or b > 6, the 3rd choice down
Answer: 49
Step-by-Step Explanation:
As we can see, we have been given a negative exponent for “x”. Hence we have to take the reciprocal which would be x squared.
Therefore, x = 7
= x^2 = 7 * 7
= 49
