Answer:
Perimeter, P = (24d+0.8) cm
Step-by-step explanation:
Given that,
Width of rectangle, B = (4.4d−4.3) cm
Length, l = (7.6d+4.7)
Perimeter is equal to the sum of all sides. A rectangle have 4 sides. The opposite sides of a rectangle are equal. So,
Perimeter = 2(L+B)
P = 2[(7.6d+4.7)+(4.4d−4.3)]
Collecting like terms
P = 2[(7.6d+4.4d)+(4.7−4.3)]
P=2(12d+0.4)
⇒ P = 24d+0.8
So, the expression for the perimeter of the rectangle is (24d+0.8) cm.

Answer:
8/3
Step-by-step explanation:
log(9x)base 2 -log (3) base 2=3
log(9x/3)base 2 =3
9x/3=2^3
3x=8
x=8/3
