Mathematics
1 answer:
anzhelika [568]2 years ago
4 0

Answer:

Step-by-step explanation:

x² - 24x + 5 = 0

x² - 24x = -5

Now divide the co efficient of x by 2 and square the quotient and add to both sides

24/2 = 12

12² = 144. Now add 144 to both sides of the equation.

x² - 24x + 144 = 5 + 144

x² - 24x  + 144 = 149

x² - 2*12*x + 12² = 149

(x  - 12)² = 149

Both sides take square root

x - 12  = ±√149

x = 12 ± √149

Vilka [71]
The dimensions of the smaller box are half those of the larger box. This means that:
*Length of smaller box= length of larger box/2= 24/2= 12cm.
*height of smaller box= height of larger box/2= 30/2= 15cm.
*width of smaller box= width of larger box/2= 10/2= 5cm.
