Answer:
=−13m−28
Step-by-step explanation:
Let's simplify step-by-step.
2−13m−30
=2+−13m+−30
Combine Like Terms:
=2+−13m+−30
=(−13m)+(2+−30)
=−13m+−28
Since the triangle is cut in half, I’m guessing it’s 22.5
Answer:
The answer to your question is 3x + 2
Step-by-step explanation:
Data
Area of the base = 2x² + 3x in²
Volume of the prism = 6x³ + 13x² + 6x in³
Height = ?
Process
1.- Divide the Volume of the prism by the area of the base to get the height
3x + 2
2x² + 3x 6x³ + 13x² + 6x
-6x³ - 9x²
0 + 4x² + 6x
- 2x² - 6x
0 0
2.- Conclusion
The height of the rectangular prism is 3x + 2
Answer:
x=-2
Step-by-step explanation:
-9x+1=-x+17
Add 9x on both sides:
1=8x+17
Subtract 17 on both sides:
-16=8x
Divide both sides by 8:
-2=x
Check x=-2!
-9x+1=-x+17 with x=-2
-9(-2)+1=-(-2)+17
18+1=2+17
19=19
19=19 is a true equation so x=-2 is correct.
Answer:
4, (31 +48), (31+66)
4, 79, 97
Step-by-step explanation:
4 + (x + 48) + (x + 66) = 180 ( sum of angles in a triangle)
4 + 48 + 66 + x + x = 180
118 + 2x = 180
2x = 180 -118
2x = 62
x = 62/2 = 31
