25x^2+1=5 quadratic
Olenka [21]
25x² + 1 = 5

25x² + 1 - 5 = 0

25x²  - 4 = 0          By difference of two squares

(5x)² - (2)² = 0

(5x - 2)(5x + 2) = 0

5x - 2 = 0    or          5x + 2 = 0

5x = 0 + 2                5x = 0 - 2

5x = 2                      5x = -2 

x = 2/5                      x = -2/5

x = 0.4                      x = -0.4 
 

x = + 0.4  or -0.4

A total of h males and (h - 2) females visit the museum on a certain day. If total of visitors for that day is 80, what is the v
Akimi4 [234]

Given:

Number of males = h

Number of females = (h-2)

Total number of visitors = 80

To find:

The value of h.

Solution:

We have,

Number of males = h

Number of females = (h-2)

So, the total number of visitors is:

Total=h+(h-2)

Total=2h-2

It is given that the total number of visitors is 80. So,

2h-2=80

2h=80+2

2h=82

Divide both sides by 2.

h=\dfrac{82}{2}

h=41

Therefore, the correct option is D.
