What is the value of x, such that the perimeter of the rectangle shown is at least 48 centimeters? if the length is (4+x)cm and the width is 3x cm​

Sagot :

Answer:

x=5

Step-by-step explanation:

P=2L + 2w

substitute

48= 4+x + 4+x +3x + 3x

combine like terms

48 = 8x + 8

single out the x

48-8 = 8x + 8 - 8

40 = 8x

40/8 = 8x/8

5 = x

x=5

sorry if my explanation is bad
