Answer:
(15)(0.75) and 0.7(15 – x) + 0.9x
Step-by-step explanation:
I did that assignment.
 
        
                    
             
        
        
        
Each sides are equal so the answer 400 cubic in
        
             
        
        
        
In tue picture, we can see 2 triangles and they already labeled 2 congruent sides. We also see that the line in the middle is being shared between the 2 triangles, making the side equal. Using the SSS theorem, we can prove that these teiangles are congruent to each other. Hope this helps.
        
             
        
        
        
Answer:
99
Step-by-step explanation:
8 + 7(4^2 - 3)
Solve what’s in the parentheses first, starting with 4^2:
8 + 7(16 - 3)
Continue solving what’s in the parentheses:
8 + 7(13)
Considering the order of operations, multiply 7(13) before adding 8:
8 + 91 = 99
 
        
             
        
        
        
Let the number be x, the square of x is x^2, then
The product of the square of x and 5 is 5x^2.
