Synthetic division for x^2+10x+21/x+3
asambeis [7]
X^2+10x+21/x+3?  If you meant (<span>x^2+10x+21)/(x+3), please note that those parentheses are essential.

If you wish to divide </span><span>x^2+10x+21 by (x+3) using synth. div., use the divisor -3:
 
                                        _______________
                                   -3 /    1      10      21  
                                                     -3      -21
                                         -----------------------
                                              1       7        0

Since the remainder is 0, (x+3) is a divisor of </span><span>x^2+10x+21, and the other factor is (1x + 7).</span><span>

The perimeter is 54 m. The apothem is \root(3)(3) . To the nearest tenth, what is the area of this regular polygon?
Serjik [45]

The area of this regular polygon is 46.8 square units

<h3>How to determine the area of this regular polygon?</h3>

The given parameters are:

Perimeter, p = 54 m

Apothem, a = √3

The area of this regular polygon is then calculated as:

Area = 0.5 * Apothem * Perimeter

Substitute the known values in the above equation

Area = 0.5 * √3 *  54

Evaluate the product

Area = 46.8

Hence, the area of this regular polygon is 46.8 square units
