Which polynomial expression represents the area of the outer most square tile, shown below?

ANSWER

EXPLANATION

The outermost square tile has side length,

The area of a square is given by;

We substitite the given expression for the side length into the formula to obtain,

We expand using the distributive property to obtain;

This gives us:

The last choice is correct.

The answer is:

The last option,

The area of square is given by the following formula:

Where, l is the side of the square, remember that a square has equal sides.

To solve the problem, we must remember the following notable product:

So, if the side of the given circle is (x-3), the area will be:

Applying the notable product, we have:

So, the correct option is the last option:

Have a nice day!

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
