2(x + 3) + 2x = 24

2x + 6 + 2x = 24

4x = 24 - 6

4x = 18

x = 3.5

length is (x + 3), so Sub x = 3.5 into (x + 3)

3.5 + 3 = 6.5

torisob [31]

Answer:

x =  - 4\: or \: x =  9

Step-by-step explanation:

make one side equal to zero:

{x}^{2}  - 5x - 36 = 0

find two factors that multiply to -36 and add to -5 (-9 & 4)

{x }^{2}  - 9x + 4x - 36 = 0

factorise

x(x - 9) + 4(x - 9) = 0

(x + 4)(x - 9) = 0

solve for x

x =  - 4 \: or \: x = 9
