Answer:4x^2 +28x +49=(2x +7)^2
Step-by-step explanation:
a2±2ab+b2=(a±b)2
In this case
a=2x and b=7 ...
4x2+28x+49=(2x)2+(2⋅
(2x)⋅
7)+72=(2x+7)2
Answer:
The total surface area of the given shape is
= 253.5 
Step-by-step explanation:
Side of the square = 6.5 in
We know that area of the square is given by the equation
⇒ A = 
Put the value of a in above equation we get
⇒ A = 6.5 × 6.5
⇒ A = 42.25 
We know that the given shape has 6 surfaces so total surface area of the given shape is given by
⇒
= 6 × 42.25
⇒
= 253.5 
Therefore the total surface area of the given shape is
= 253.5
