Answer:

100-x^2

Step-by-step explanation:

Length of the Blue Square = 10 inch

Length of the Red Square = x inch

Area of a Square =l^2

The Area of the Blue Band = Area of the Blue Square - Area of the Red Square

=(10^2)-x^2\\=100-x^2

The area of the blue band is 100-x^2

What is the simplified form of the expression 11[6^2/(5^2-4^2)+7]
earnstyle [38]

Answer:

  121

Step-by-step explanation:

A calculator can answer this for you.

_____

Following the steps of the <em>order of operations</em>, you evaluate inner parentheses first. The exponents are the first to be evaluated there.

  11[6^2/(5^2-4^2)+7]

  = 11[6^2/(25 -16)+7]

  = 11[6^2/9 +7]

Then you do the exponent ...

  = 11[36/9 +7]

Now you do the division ...

  = 11[4 +7]

And finally, you can finish up the outer parentheses ...

  = 11·11

  = 121
