set them equal to each other and reverse pemdas as shown in my image
 
        
        
        
the answer is 4.5 ft
Step-by-step explanation:
Step-by-step explanation:
Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,
18/x = 8/2
Let's solve for x as required.
We have,
18/x = 8/2
=>Cross multiply:
18 × 2 = 8 × x
36 = 8x
=>Divide both sides by 8
36/8 = x
4.5 = x
x = 4.5 ft
 
        
             
        
        
        
Answer:
96
Step-by-step explanation:
 
        
                    
             
        
        
        
Start by combining like terms: 


Now we have:

Divide both sides by 2 to isolate s

Final answer:
s=12
 
        
        
        
3. Here we use the formula

And we have the following values given

So we will get

Question 4.
