The width is half the length, so is
width = (1/2)*length
width = (1/2)*(<span>3.2a + 0.18b) cm
width = (1.6a +0.09b) cm
The perimeter of the rectangle is twice the sum of length and width.
perimeter = 2*(length + width)
perimeter = 2*((3.2a +0.18b) cm + (1.6a +0.09b) cm)
perimeter = 2*(4.8a +0.27b) cm)
perimeter = (9.6a +0.54b) cm

Answer:
Step-by-step explanation:
- 13t - 3t = (13 - 3)t = 10t
- 3t - 13t = (3 - 13)t = -10t
- 10t ≠ -10t
They are not equivalent
<u>When t = 2</u>
- 13t - 3t = 13*2 - 3*2 = 26 - 6 = 20
- 3t - 13t = 3*2 - 13*2 = 6 - 26 = -20
Part A: Linear function
explanation:
The table for the value of the two cars with time are given as follows;
Years Car 1 Car 2
1 18,500 18,500
2 17,390 17,500
3 16,500 16,346.6
Plotting the give data, we have;
From the plot of the data, the function that can be used to describe the values of both cars after a fixed number of years is a linear function
Hope this helps a bit
