The height of a triangle is 8 yd longer than the base x. The area is 192 yd?
sineoko [7]

Answer:

192 = (x^2 + 8x)/2

Step-by-step explanation:

we know the base is x and the height is x+8.

Area of the triangle is 1/2 bh.

we know h and x

if we take area to be 192, we can write the area to be;

1/2 x(x+8) =A

192 =\frac{x^{2}+8x }{2}\\

If you have 120 feet of fencing and want to enclose a rectangular area up against a long, straight wall, what is the largest are
Tems11 [23]
The area of rectangular is  A= length x width
 
  120 feet of fancing = ---------------------------------- (the above line)


        !-----------------------------------------!                                     
        !                                                   !
     x !   the enclosed area                 ! x
        !                                                   !
        !---------------------------------------- !
                          120 -(x+x)
so the area is  A = (120-2x) (x)= 120x-2x²
