The length of a rectangle is 3 centimeters less than twice its width. The perimeter of the rectangle is 48 cm. What are the dime

Vlada [557]

The equation for the length is L=2W - 3. The perimeter is 48 cm and the equation for finding the perimeter is P = 2W + 2L. Substitute the formula of L into the formula for perimeter and solve algebraically:

$P = 2W +2L \\ 48= 2W + 2(2W-3) \\ 48=2W + 4W - 6 \\ 48 = 6W - 6 \\ 48+6 = 6W \\ 54=6W \\ W=9 \\ L=2(9)-3 = 15$

The correct answer is A) length = 15cm; width = 9cm

What is the sum of interior angles of a 53-gon? Type just the number, no words, letters, or symbols

MissTica

Answer:

S = 9180°

Step-by-step explanation:

Given the following data;

Number of sides = 53

To find the sum of interior angles of a 53-gon;

Mathematically, the sum of the interior angles in a regular polygon is given by the formula;

S = 180(n - 2)

Where;

n is the number of sides.

S is the sum of the interior angles

Substituting into the formula, we have;

S = 180(53 - 2)

S = 180 * 51

S = 9180°
