Answer:
Step-by-step explanation:
The total surface area of this triangular prism consists of three rectangles and two triangles. Adding the areas of each of these shapes allows us to find the total surface area of this 3D figure:
Area of both triangles:
Area of all three rectangles:
Therefore, the total surface area of this figure is:
Answer:
He saved 58 last month.
Step-by-step explanation:
All expenses: 625 + 259 = 884

Answer:
the mean is greater than the median
3r-6=-21
3r-6+6=-21+6 (Add 6 to both sides...)
3r=-15
r=-5
3r-6=21
3r-6+6=21+6 (Add 6 to both sides...)
3r=27
r=9
r=-5 or r=9
Answer:
n <=6.5
Step-by-step explanation:
Six less than two times a number is no more than 7
2n-6 <=7
Add 6 to each side
2n-6+6 <=7+6
2n <=13
Divide by 2
2n/2 <=13/2
n <=6.5
