Tan (x) = 0.8. To calculate the angle x, find the tan⁻¹ (0.8) = 38.7°
1. Add 4x back into -2, you now have -4y=-4x-2. Add +4 from y and now you are at y=-4x+2 and this is the answer!
2. Add -9x back into -3, you now have -4y=9x-3. Add +4 from y and now you are at y=9x-7 and this is your answer!!
I hope this helped! Brainliest? :) -Raven❤️
10x
8x-2
6x+4
They all simplify
Answer:
8n
Step-by-step explanation:
The surface area of a shape is the amount of space on the shape
When the dimensions are quadrupled, the new surface area would be 16 times the initial surface area
<h3>How to determine the surface area</h3>
The surface area of a rectangular prism is:

When quadrupled, we have:

Factor out 16

Substitute 

The above means that:
The new surface area would be 16 times the initial surface area
