Answer:

(x+2)(x+10)

Step-by-step explanation:

The given trinomial needs to be factorised. On the basis of degree of power of polynomial it can also be called a quadratic polynomial . General form is ax² + bx + c .

= x² + 12x + 20

  • By splitting middle term .

= x² + 10x + 2x + 20

  • Taking x and 2 as common.

= x ( x + 10 ) + 2( x + 10 )

  • Talking (x + 10) as Common .

= ( x + 2)( x +10)

<h3><u>Hence</u><u> </u><u>the</u><u> </u><u>factorised</u><u> </u><u>form</u><u> </u><u>is</u><u> </u><u>(</u><u>x</u><u>+</u><u>2</u><u>)</u><u>(</u><u>x</u><u>+</u><u>1</u><u>0</u><u>)</u><u>.</u></h3>

dezoksy [38]

Answer:

12/30

Step-by-step explanation:

So we know that the denominator-numerator=18

And we also know that it's equal to 4/10 or 2/5.

Soooooooooooooo the most easiest is just to trial and error: 12/30

But I don't really know the more complex formula...

In triangle abc, the angle c is six times as large as angle
mote1985 [20]
The interior angles of a triangle add up to 180 degrees

a = 1st angle, b = 2nd angle, c = 3rd angle

c = 6a
b = a + 60
a + b + c = 180

a + (a + 60) + (6a) = 180
8a + 60 = 180
8a = 180 - 60
8a = 120
a = 120/8
a = 15 <=== here is one angle

b = a + 60
b = 15 + 60
b = 75 <=== and another one

c = 6a
c = 6(15)
c = 90 <=== and the last angle
