Answer:
The surface area of the rectangular prism is 748 ft2.
Step-by-step explanation:
formula for surface area: A=2(wl+hl+hw)
A=2(wl+hl+hw)=2(5x16+14x16+14x5)=748
 
        
                    
             
        
        
        
Answer:
4
Step-by-step explanation:
 Equation 1
 Equation 1
 Equation 2
 Equation 2
What is the value of  where each variable represents a real number?
 where each variable represents a real number?
Let's expand equation 1:


Simplify each term if can:

See if we can factor a little to get some of the left hand side of equation 2:
The first two terms have  and if I factored
 and if I factored  from first two terms I would have
 from first two terms I would have  which is the first term of left hand side of equation 2.
 which is the first term of left hand side of equation 2.
So let's see what happens if we gather the terms together that have the same variable squared together.

Factor the variable squared terms out of each binomial pairing:

Replace the sum of those first three terms with what it equals which is 6 from the equation 2:

Combine like terms:

Subtract 6 on both sides:

Divide both sides by 3:

 
        
             
        
        
        
The first one is correct (-2/3, -1/2, 7/12, 0.82) pls mark branliest
        
                    
             
        
        
        
I’m not too sure if I did it correct, but the answer I got was -6x^2+36. I just assumed you’d solve it as usual and then multiply (-3) after distributing-2 to x^2-6. Hope this helps.
 
        
        
        
I think the answer is C. 45 units
