The area of a parallelogram is 15ft^2 and the height is 5ft. Find the length of the corresponding base.
Roman55 [17]

Answer:

To find the missing base, you simply divided the area by the given height. This will work the same way if you are looking for the height. To find the missing height, divide the area by the given base. Consider this parallelogram where height is the missing dimension.Oct 30, 2012

Which steps could be part of the process in algebraically solving the system of equations, y + 5x = x2 + 10 and y = 4x – 10? Sel
dolphi86 [110]

Answer:

That would be :

 4x – 10 = x2 – 5x + 10  ( y = 4x - 10 is substitute for y)

 PROOF:        y + 5x = x² + 10

                     (4x - 10) + 5x = x² + 10

                      4x - 10  =  x² -5x + 10

    0 = x2 – 9x + 20  (liked terms are grouped and simplified)

PROOF:      4x - 10  =  x² -5x + 10

                   4x = x² -5x + 10 + 10

                    0  = x² -5x -4x + 20

                    0  = x² - 9x + 20

Solving:

             x² - 9x + 20 = 0 

             x² - 5x - 4x + 20 = 0

             (x - 5) (x - 4)  = 0

          ⇒ x = 4  (as question says) OR x = 5
