Answer:
c=11×(450+250)-90
Mrs. Shin owes $7610
Step-by-step explanation:
use pemdas to find total amount owed
Area Of Rectangle
= 2 length × 2 width
= 2 l + 2 w
l = 2 w -3................equation (i)
2 l + 2 w = 42..........equation (ii)
2(2 w -3) + 2 w =42
4 w - 6 + 2 w = 42
4 w + 2 w = 42 + 6
6 w = 48
w =8
l = 2 w - 3
l = 2×8 - 3
l = 13
Length = 13
Width = 8
C = 48
c = 2a - 4
48 = 2a - 4
48 + 4 = 2a
52 = 2a
52/2 = a
26 = a <==
When talking about object measurements, we usually require they be positive.
A suitable domain is x > 0.
(and somewhat less than any substantial fraction of the Earth's dimensions. The numerical value will depend on the chosen units.)
The answer is 530. I’m pretty sure
