Answer:
![Area = 27cm^2](https://tex.z-dn.net/?f=Area%20%3D%2027cm%5E2)
![P=23cm](https://tex.z-dn.net/?f=P%3D23cm)
Step-by-step explanation:
Required
The area and the perimeter
Solving (a): The area
The shape is a composite figure withe following characteristics:
Rectangle 1: 3cm by 5cm
Rectangle 2: 2cm by 6cm
So, the area is the sum of the areas of both rectangles
![Area = 3cm * 5cm + 2cm*6cm](https://tex.z-dn.net/?f=Area%20%3D%203cm%20%2A%205cm%20%2B%202cm%2A6cm)
![Area = 15cm^2 + 12cm^2](https://tex.z-dn.net/?f=Area%20%3D%2015cm%5E2%20%2B%2012cm%5E2)
![Area = 27cm^2](https://tex.z-dn.net/?f=Area%20%3D%2027cm%5E2)
Solving (b): The perimeter
This is calculated as:
--- sum of all lengths
![P=23cm](https://tex.z-dn.net/?f=P%3D23cm)
Answer:
A. Yes, the slope is the same between each pair of points
Step-by-step explanation:
First of all, B and D are stating 2 opposite things in the same sentence, allowing us to instantly eliminate those choices. Second of all, you got C, and it said it was wrong, which makes sense because it does show a constant rate of change. This concludes by process of elimination, that the answer is A. Third of all, I hope this helps!
Good Morning hope this helped.

3: $2 every time
Answer:
Step-by-step explanation:
Easy way: type the equation into a graphing calculator.
__
By hand: find a couple of points and draw a line through them.
The equation is in "slope-intercept" form:
y = mx + b
where m is the slope (-2) and b is the y-intercept (3). The y-intercept is where the line crosses the y-axis, so right away you know one point on the line. That point is (0, 3).
The slope of -2 means for each horizontal unit, the line drops 2 units vertically. The point 1 unit to the right of (0, 3) is (1, 3); and the point 2 units below that is (1, 3-2) = (1, 1). So, another point on the line is (1, 1).
You can plot those two points and draw the line through them.
