Answer:

The answer is 8 .

Step-by-step explanation:

f(x)=36

36=3x+12

36-12 and 12 -12

36-12=24

24 divided by the 3 that left in the equation equals 8 .

36=3x+12

-12       -12

24=3x

divided 24 by 3 and get 8

ratelena [41]

Answer: Width = 3cm

Length = 8cm

Step-by-step explanation:

Length = x+5 cm

Width = xcm

Area = 24cm²

Area of a rectangle = length × width

x × (x + 5) = 24

x² + 5x = 24

x² + 5x - 24 = 0

x² + 8x - 3x - 24 = 0

x(x + 8) - 3(x + 8) = 0

x - 3 = 0

x = 3

Width = 3cm

Since length = x + 5 = 3 + 5 = 8cm

Length = 8cm
