Answer:
All the rational roots of the polynomial f(x) = 20x4 + x3 + 8x2 + x - 12 are 3/4 and -4/5.
Answer:
3(6 + a) = 69
Step-by-step explanation:
Let the unknown number be a
3(6+a) = 69
18 + 3a = 69
3a = 69-18
3a = 51
a = 51/3
a = 17
F(3) is equal to -4 or letter b coordinate
Use distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
(11,-4) is (x1,y1) and (-12,-4) is (x2,y2)
Plug in and simplify
d = sqrt((-12 - 11)^2 + (-4 - -4)^2)
d = sqrt((-23)^2 + (0)^2)
d = sqrt(529 + 0)
d = sqrt(529)
d = 23 (positive because length cannot be negative)
