Answer:
The answer is option B
Step-by-step explanation:
The solution is in the image
The y-intercept (where x = 0) of the equation is at -20.
For every 60 the x runs, the y falls by -10. Use rise over run to determine the slope of the equation.

Slope-intercept form is determined by the following equation:

m is your slope, and b is your y-intercept.
Plug the slope and y-intercept into the equation.
If you multiply 8.5 by 50 cents your answer will be 4.25
Answer:
cm²
Step-by-step explanation:
Surface area of the composite figure = Surface area of the lateral surfaces of the given pyramids
Lateral surface area of a square pyramid = 4
Therefore, lateral surface area of the pyramid
= ![4[\frac{1}{2}(24)(5)]](https://tex.z-dn.net/?f=4%5B%5Cfrac%7B1%7D%7B2%7D%2824%29%285%29%5D)
Now lateral surface area of the composite figure = 2(lateral surface area of two pyramids)
= ![8[\frac{1}{2}(24)(5)]](https://tex.z-dn.net/?f=8%5B%5Cfrac%7B1%7D%7B2%7D%2824%29%285%29%5D)
Therefore, Expression for the surface area of the given composite figure is,
cm²
