Using the surface area formula for rectangular and triangular prism, the surface area of the composite figure is: 444 m².
<h3>What is the Surface Area of the Composite Figure?</h3>
Total surface area = surface area of the top triangular prism + surface area of the bottom rectangular prism - area of the surface both share together.
Surface area of the top triangular prism = (S1 + S2+ S3)L + bh = (10 + 10 + 16)5 + (16)(6) = 276 m².
Surface area of the bottom rectangular prism = 2(wl + hl + hw) = 2·(5·16+4·16+4·5) = 328 m²
Area of the surface both share together = 2(16)(5) = 160 m²
Total surface area = 276 + 328 - 160 = 444 m².

Answer:  (6a + 5b) • (6a - 5b)
  
Reformatting the input :
Changes made to your input should not affect the solution:
 (1): "b2"   was replaced by   "b^2".  1 more similar replacement(s).
Step by step solution :
Step  1  :
Equation at the end of step  1  :
  (36 • (a2)) -  52b2
 Step  2  :
Equation at the end of step  2  :
  (22•32a2) -  52b2
Step  3  :
Trying to factor as a Difference of Squares :
 3.1      Factoring:  36a2-25b2 
Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)
Proof :  (A+B) • (A-B) =
         A2 - AB + BA - B2 =
         A2 - AB + AB - B2 =
         A2 - B2
Note :  AB = BA is the commutative property of multiplication.
Note :  - AB + AB equals zero and is therefore eliminated from the expression.
Check :  36  is the square of  6 
Check : 25 is the square of 5
Check :  a2  is the square of  a1 
Check :  b2  is the square of  b1 
Factorization is :       (6a + 5b)  •  (6a - 5b) 
Final result :
  (6a + 5b) • (6a - 5b)

Answer:
x=3 or x=−9
Step-by-step explanation:
Step 1: Subtract 27 from both sides.
x2+6x−27=27−27
x2+6x−27=0
Step 2: Factor left side of equation.
(x−3)(x+9)=0
Step 3: Set factors equal to 0.
x−3=0 or x+9=0
x=3 or x=−9
Answer:
x=3 or x=−9
 
        
                    
             
        
        
        
Answer:
x2+11x+28     
Step-by-step explanation:
Thus, (x+7)(x+4) multiplies out to x2+4x+7x+28, which can be simplified to        
                                                      x2+11x+28
