Cho hàm số y = x^3 + (m+1)x^2 + (2m-1)x+6. Tìm m để hàm số a) đạt cực đại tại x=-2
b) đạt cực tiểu tại x =5
c) có hai cực trị

21/58.

hope to be marked brainliest

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
