Answer: OPTION D
Step-by-step explanation:
To solve this problem you must apply the formula for calculate the surface area of the rectangular prism:
Where w is the width, h is the heigh and l is the lenght.
Based on the rectangular prism shown, you have that:
Finally when you substitute values into the formula you obtain the following result:
![SA=2[(9.08cm*3.23cm)+(11.73cm*9.08cm)+(11.73cm*3.23cm)]=347.45cm^2](https://tex.z-dn.net/?f=SA%3D2%5B%289.08cm%2A3.23cm%29%2B%2811.73cm%2A9.08cm%29%2B%2811.73cm%2A3.23cm%29%5D%3D347.45cm%5E2)
Answer:
1.3c-3.7
Step-by-step explanation:
5.2c-3.9c=1.3
-7.35+3.65=-3.7
1.3c-3.7
The price reduced from 250 to 200, so it is -50

Answer: Slope = -3</h3>
=======================================================
Explanation:
Pick any two rows you want. I'll pick the middle two rows where every value is positive. So I'll pick these two rows:
- x = 0 and y = 4
- x = 1 and y = 1
They lead to the points (0,4) and (1,1). Apply the slope formula for these rows.
m = (y2-y1)/(x2-x1)
m = (1-4)/(1-0)
m = -3/1
m = -3
The slope is -3
