Answer:
the 3rd one
Step-by-step explanation:
A = 9 and b = 6 are the two given sides
The third missing side n can be described through the following inequality
a-b < n < a+b
where a > b ('a' is larger than b)
This is the triangle inequality theorem
So,
a-b < n < a+b
9-6 < n < 9+6
3 < n < 15
Answer: 3 < n < 15
(which means you can pick any number from 3 to 15 for n. You cannot pick 3. You cannot pick 15)<span />
2x^2 + 5x + 2 = (2x + 1)(x + 2)
2w^2 + 5w - 3 = (2w -1)(w + 3)
3a^2 + 14a + 8 = (3a + 2)(a + 4)
30z^2 - 23z + 2 = (10z - 1)(3z - 2)
8y^2 + 23y -3 = (8y - 1)(y + 3)
not sure about last one sorry
Answer:
Option A , (0, 20); y equals one over eighty times x squared plus 20
Step-by-step explanation:
The equation of parabola is given by
(X-h)^2 = 4p(Y-k)^2
In this case h = 0
So we get
Y = X^2/4P +k
Focus point is (h, p+k) , p+k = 40
Hence h, k = (0,20)
P = 40-k = 20
Equation Y = X^2/80 +20
Hence, option A is correct

Answer:
x = 3 or x = -3
Step-by-step explanation:
The absolute value of 3x = 9
Divide nine by 3 to get 3
Absolute value represents the number of spaces an integer is from 0, so the answer could also be -3, as the absolute value of 3 x -3 (-9) is 9.
