Step-by-step explanation:
Answer:
The school would have to give $300 and each side would be 100cm
Step-by-step explanation:
(4x - 8)cm = Side length
Solve for X
3(4x - 8) = 300
(Getting rid of the three)
(12x -24) = 300
(Getting rid of the 24)
(12x) = 324
(Getting rid of the 12)
(12x/12) = 324/12
X = 27
27 x 4
Side length = (108 - 8)
108 - 8 = 100cm
100 x 3 = 300cm (1cm = $1)
$300
Each Side would be 100cm
Answer:
f(g(x)) = x² - 5x +4
Step-by-step explanation:
<u><em>Explanation</em></u>
Given that the functions
f(x) = x² + 3 x and g(x) = x-4
f(g(x)) = f(x -4) (∵ g(x) = x-4)
= (x-4)² + 3(x-4)
= x² - 2(4)x + 4² + 3x -12
= x² - 8 x + 16 + 3x -12
= x² - 5x +4
∴ f(g(x)) = x² - 5x +4
3/8 as a percentage is 37.5%
