-<span>6(24x + 18) = 43(5 + 5x)

-144x - 108 = 215 + 215x

-108 - 215 = 215x + 144x

-323 = 359x 

x = - 323/359       </span>⇒ Answer B. One solution in <span>ℝ</span>

The answer is B 

<span>-6(24x+18)=43(5+5x)
-144x - 108 = 215 +215x
-108 = 215 + 359x
-323 = 359x 
-323/359 = x

If you would like me to explain more details i will!</span>

Anyone know the area?
Elina [12.6K]
Answer:  The area of the triangle is:  " 8.5 cm² " ; 

                                         or, write as:  " 8\frac{1}{2} cm² " .
_______________________________________________________
Explanation:
_________________________________________________________
The formula {"equation"} for the area of a triangle is:

A = (\frac{1}{2}) * b * h ;
   
in which:  A = area; 
                 b = base;
                 h = [perpendicular] height;
___________________________________
{also, can be written as:  " A = (b * h) / 2 " .}.
______________________________________
Solve for the area, "A" ; by plugging in the known values shown in the figure (image attached):
______________________________________
                             base, "b" = 13 cm ;
[perpendicular] height, "h" =  5 cm ;
______________________________________
A = (b * h) / 2 ;

   = (13 cm * 5 cm) / 2 ; 

   = [ (13 * 5) cm²] / 2 ; 

    = 65 cm² / 2 ;

A  = " 8.5 cm² " ; or, write as:  " 8\frac{1}{2} cm² " .
_________________________________________________________
Answer:  " 8.5 cm² " ; or, write as:  " 8\frac{1}{2} cm² " .

How do I do this? 50 points, please answer
xz_007 [3.2K]

Check the picture below.

now, the midsegment of a triangle, besides being half the base, we have to bear in mind that is a "mid" segment, is a segment that lies half-way along the segments it touches.

so for the triangle above, well, the midsegment DE is cutting the segment BC it two equal halves, BE and EC, that means that \stackrel{x}{BE}~~ = ~~\stackrel{8}{EC}.
