HELP MATES, HELP! <br> Mustafa was asked whether the following equation is an identity:
melamori03 [73]

Answer: Mustafa is incorrect. He made a mistake in step 2.

Step-by-step explanation: Mustafa was certainly correct in step 1 that x(9x+3) + 3(x+3) is 9x^2 + 6x + 9. However when he was factoring, he made a mistake.

(3x + 3)^2 is NOT equal to 9x^2 + 6x + 9. Rather, (3x + 3)^2 is equal to 9x^2 + 18x + 9. If you want to double check this, use FOIL.

The correct factoring of 9x^2 + 6x + 9 is actually 3(3x^2 + 2x + 3). So, Mustafa made a mistake in step 2.

The length of a rectangle is 4.2 cm more than 2 times the width. If the perimeter of the rectangle is 42.6 cm, what are its dime
Tema [17]

Hi there!

The general formula to find the perimeter of a rectangle is :

P = (Length × 2) + (Width × 2)

Let's say the width of the rectangle is "x".

The lenght of the rectangle is equal to 2x + 4.2


Replace everything you know in the formula :

42.6 = ((2x + 4.2) × 2) + ((x) × 2)


Simplify everything :

2x × 2 = 4x

4.2 × 2 = 8.4

x × 2 = 2x


42.6 = 4x + 8.4 + 2x

42.6 = 6x + 8.4


Isolate "x":

42.6 = 6x + 8.4

Subtract 8.4 from each side of the equation

34.2 = 6x

Divide each side of the equation by 6

5.7 = x

5.7cm = the width of the rectangle


Since the lenght of the rectangle is equal to 2 times the width of the rectangle plus 4.2 :

Length = (2 × 5.7) + 4.2

Length = 15.6cm


42.6 = (2 × 15.6) + (2 × 5.7) ? → YES


There you go! I really hope this helped, if there's anything just let me know! :)
