The absolute value sign changes anything that's in it to become a positive number. So -9 + 4 is -5. The | <--absolute value signs--> | will make the -5 becomes positive. So |-5| = 5.
Your answer is 5.
Answer:
Step-by-step explanation:
Put the numbers that represents tacos, enchiladas and tamales in front of x, y and z
For instance,
2x+2y+1z=8.50
3x+2y+2z=13
1x+3y+2z=11.50
Answer:
15 < n < 25
Step-by-step explanation:
According to the triangle inequality theorem, any two sides lengths' sum should be greater than the third side. This also implies that to find the <em>possible length of the 3rd side given other two sides (let two given sides be x and y)</em>, we can say that the 3rd side length will be between x+y and x-y.
Hence, we can say that <em><u>n should be between 20+5 and 20-5</u></em>.
So, 20 - 5 < n < 20 + 5, which is
15 < n < 25
<em>This is the correct answer.</em>
Answer:
Second Option
671 m²; 725 m²
Step-by-step explanation:
The lateral area of a triangular prism is:
Where P is the perimeter of the triangular base and h is the height of the prism.
In this case, the perimeter of the triangular base is:
Then the height is 26 m
Then the lateral area of the prism is:
Therefore the surface area of the triangular prism is:
Where 
is the area of the base.
Where b is the base of the triangle and h is the height
In this case:
Finally
The answer is 671 m² and 725 m²
