Answer:
8
Step-by-step explanation:
well because since you have to add u add 3+b
Answer:
hole at x=-3
Step-by-step explanation:
The hole is the discontinuity that exists after the fraction reduces. (Still doesn't exist for original of course)
The discontinuities for this expression is when the bottom is 0. x^2-9=0 when x=3 or x=-3 since squaring either and then subtracting 9 would lead to 0.
So anyways we have (x+3)/(x^2-9)
= (x+3)/((x-3)(x+3))
Now this equals 1/(x-3) with a hole at x=-3 since the x+3 factor was "cancelled" from the denominator.
The number is 14
Here's the solution:
Let the number be x
According to the question,
27+7x=125
//Subtract 27 from both the sides
7x=125-27
7x=98
//divide both the sides by 7
x=98/7
x=14
I guess sides and angles !
