14 + 14 = 28

 

[Trainee]

Ningekuwa daslama ningewatafuta pyaar, chamoto, eroni na lwiva ili wanifundishe au wanifundishie mwanangu

Nadhani kwa collabo hiyo ningekuwa mbali mno

 

[Chamoto]

Hahaha!
Yupo sahihi

X cube root 3 - 27 =0
X cube root 3 -27 + 27 = 0 + 27
X cube root 3 = 27
ie. 3 x 3 x 3
X = 3

Njia sahihi ya kupata roots zote za x³ - 27 = 0 ni hii;

x³ - 27 = 0
x³ - 3³ = 0

since a³ - b³ = (a - b)(a² + ab + b²)
(x - 3)(x² + 3x + 9) = 0

for x - 3 = 0, x =3

for (x² + 3x + 9) = 0, x = [ -3 ± 3i√3 ] / 2

Kwasababu Mshana Jr ametaka real roots basi tutampa jibu lake la x =3

Umetisha mkuu.

14 + 14 = 28

I got 20, how did you come up with 28?

 

[Pyaar]

I got 20, how did you come up with 28?

4 + 4 = 8
7 + 7 = 14
9 + 9 = 18
10 + 10 = 20

The difference;
7 -4=3
9 - 7= 2
10 - 9 = 1

1,2,3,4,5,6,7,8,9
The missing number is 4 ie. The difference between 28…(14 + 14) and 20…(10 + 10).
