Answer:
12 meters
Step-by-step explanation:
Given That :
Length of ladder = 15m
Height of wall =. 9 m
Using Pythagoras rule :
Adjacent² = hypotenus² - opposite²
Adjacent² = 15² - 9²
Adjacent² = 225 - 81
Adjacent² = 144
Adjacent = sqrt(144)
Adjacent, x = 12
Divide the total cost by all 5 panes to get the cost of 1 pane:
14.25/5 = 2.85
Then multiply by 2:
2.85 * 2 = $5.7
9 +(17 - k)
26 - k
<em>more than </em>refers to addition. <em>The difference</em> refers to subtraction. Because the value of <em>k</em> is not given, there is no equal sign, making this an algebraic expression.
