Okay!
10% of 55 is 5.5
(Butterfly method)
10/100 = n/55
10*55= 550
550/100= 5.50

30% of 900 is 270
30/100 = n/900
30*900 = 27000
27000/100 = 270

25% of 200 is 50
25/100 = n/200
25*200 = 5000
5000/100 = 50

20*4-30
80-30
50

(2*7)+12
14+ 12
26

how do i get the answer and what is the answer? im looking for a right answer not just someone who types in the mayo mayo
ankoles [38]

Answer:

x = 51°

Step-by-step explanation:

The straight line segment has a total angle of 180°. Therefore, to find the angle inside the triangle that is next to 94°, subtract 94 from 180:

180° - 94° = 86°

That angle is almost a right angle but not quite. Now, to find x, add up the two angles inside the triangle and subtract it from 180°:

43° + 86° = 129°

180° - 129° = 51°

Polynomial function in standard form with zeros 5,-4,1
Oksanka [162]

Answer:

\boxed{\sf \ \ \  x^3-2x^2-19x+20 \ \ \  }

Step-by-step explanation:

hello,

by definition we can write

(x-5)(x+4)(x-1)

as 5,-4,1 are the zeroes

now we have to write it in the standard form, let's do it

(x-5)(x+4)(x-1)=(x^2+4x-5x-20)(x-1)\\=(x^2-x-20)(x-1)=x^3-x^2-20x-x^2+x+20\\=x^3-2x^2-19x+20

hope this helps
