Step-by-step explanation:

$3 + \frac{9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{3 \times 4 + 9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{12 + 9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{21}{4} = \frac{9}{x+4} \\ \\ \therefore \:21(x + 4) = 36 \\ \\ \therefore \:21x + 84 = 36\\ \\ \therefore \:21x = 36 - 84\\ \\ \therefore \:21x = - 48\\ \\ \therefore \:x = \frac{-48}{21} \\ \\ \therefore \:x = \frac{-16}{7} \\ \\ \huge \red{ \boxed{ \therefore \:x = - 2 \frac{2}{7} }}\\ \\$

The length of a rectangle is five times its width. If the perimeter is at most 96 centimeters, what is the greatest possible val

Dvinal [7]

Let width be W

Then length = 5W

P=2L+2W

P< 96cm

Then the Perimeter of the rectangle is equal to

(2L+2W)< 96

2*(5W)+2W)≤96

Therefore, 2w+2⋅(5w)≤96

should be your answer
