Find the difference between the lengths of the longest and shortest sides of a rectangle if its area is 924 square milimetres an

BigorU [14]

Length =l

Height = h

Area function = l * h = 924

Perimeter function = 2i + 2h = 122

Divide by 2

I + h = 61.

Plug in I or h for the other variable

I * (61 - I) = 924

61i - i^2 = 924

Factor the function

(-I + 28)(I - 33) = 0

l = 33 as l cannot be negative

61 - 33 = 28

h = 28

Difference between h and l is 33-28=5

bogdanovich [222]

Answer:

15

Step-by-step explanation:

The given equation is

$12( - \frac{1}{6}x - \frac{2}{3}y = - 5)$

$5( \frac{2}{5} x + \frac{1}{5} y = - 9)$

When we multiply we obtain the equations:

$- 2x - 8y = - 60$

$2x + y = - 45$

We add both equations to obtain:

$- 7y = - 105$

Divide both sides by -7 to get:

$y = \frac{105}{7} = 15$
