Tems11 [23]
<span>Congruence between two triangles means six items, all three sides and all three angles, are congruent. Thus the statement ABC DEF has a very precise meaning. It succinctly summarizes the six statements (assume lines atop these segments): ABDE, BCEF, ACDF, AD, BE, and CF. It is very important to maintain the vertices in the proper order. Not doing so is a common mistake.</span>

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
