Answer:
2160 BTU
Step-by-step explanation:
Ben looks at his plan and realizes that his building can be viewed as a triangular prism sitting on a cube.
Calculating the volume of a cube is easy… Length x Width x Height (LWH)… so 12 x 10 x 8 = 120 x 8 = 960 cubic feet for the cube part.
For the prism, it’s almost the same… but divided by 2 : (LWH)/2, so… (12 x 10 x 2) / 2 = (120 x 2) / 2 = 240 / 2 = 120 cubic feet for the prism part.
Total for the building : 960 + 120 = 1080 cubic feet
Since 2 BTU per cubic foot, the power of the unit needs to be at least 1080 x 2 = 2160 BTU.
Answer:
<h2>x=25</h2>
Step-by-step explanation:
according to the question
the equation is
130+2x=180
2x=180-130
2x=50
x=25
No
4(x+3)=2(x+4+x+1)
4x+12=4x+10
12=10

For 3 + (-9), you should subtract 9 from 3. When you add a negative number it's the same thing as just subtracting said number. So, to solve this problem, you would change 3 + (-9) to 3 - 9, which is -6.
