FInd the surface area of the triangular prism
Marta_Voda [28]

Answer:

273.7

Step-by-step explanation:

first fine the sides that isn't the base.

triangle area formula: (b*h)/2

(14*9)/2 = 63

since there are 3 sides you multiply this by three.

63*3=189

then find the base.

same formula since its a triangle.

(12.1*14)/2 = 84.7

now add them both up:

84.7+189 = 273.7

hope this helps!

|x2+x-20<br> 22-11x+28<br> e:<br> x2-x-30<br> 3x-18
elena-s [515]

Answer:

x2 - 10x - 1994

Step-by-step explanation:

Step  1  :

Trying to factor by splitting the middle term

1.1     Factoring  x2-10x-1994

The first term is,  x2  its coefficient is  1 .

The middle term is,  -10x  its coefficient is  -10 .

The last term, "the constant", is  -1994

Step-1 : Multiply the coefficient of the first term by the constant   1 • -1994 = -1994

Step-2 : Find two factors of  -1994  whose sum equals the coefficient of the middle term, which is   -10 .

     -1994    +    1    =    -1993

     -997    +    2    =    -995

     -2    +    997    =    995

     -1    +    1994    =    1993

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 x2 - 10x - 1994
