Answer:
$12.09
Step-by-step explanation:
formula; Y= kx
where; y = $24.18
x = 2 books
k = constant of proportionality
Step 1. Do the equation based on the data given
Y = kx
$24.18 = k2
Step 2. Compute the mathematical equation. Divide both sides by 2 to eliminate coefficient in the variable.
<u>24.18 =k2</u>
2
k = $ 12.09 is the constant of proportionality cost in dlooars per book

Answer:
2sq-36
Step-by-step explanation:
sq-16+sq-25+5
sq+sq-16-25+5
2sq-41+5
2sq-36
Area A of a square with side length a: A = a².
Pythagoras theorem: a² + b² = c²
2*a² = 8²
A = 8²/2
