length of a rectangle is 5 cm longer than the width. four squares are constructed outside the rectangle such that each of the squares shares one side with the rectangle. the total area of the constructed figure is 120 cm2. what is the perimeter of the rectangle?
you to whoever answers : d

18 Centimeters

Step-by-step explanation: The area of the figure is

2x^2 + 2(x+5)^2 + x(x+5)

= 2x^2 + 2x^2 + 20x + 50 + x^2 + 5x

= 5x^2 + 25x + 50,

and this is 120 cm^2,

so x^2 + 5x + 10 = 24 =>

x^2 + 5x - 14 = 0 =>

x = 2, (as x can't be -7).

The perimeter of the original rectangle is

4+14=18 CM

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
