About 7
because 5^2+5^2 is 50 and then you take the sq root of 50 which is about 7
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.
V + f - e = 2
e = v + f - 2
Answer:
Yes
Step-by-step explanation:
80² + 150² = 170²
6400 + 22500 = 28900
28900 = 28900
