Answer:
286
Step-by-step explanation:
If the three-digit number is xyz, then:
x + y + z = 16
y = z + 2
z = 3x
Substitute the third equation into the second:
y = 3x + 2
Substitute this and the third equation into the first:
x + (3x + 2) + (3x) = 16
7x + 2 = 16
7x = 14
x = 2
y = 3x + 2 = 8
z = 3x = 6
The number is 286.
2^3 is equivalent because if you count the number of twos there are in the parentheses its 3.
It’s likely scalene since none of the angles are the same
Volume=legnth times width times height
legnth=8
width=5
height=4
volume=8 times 5 times 4=160
volume is 160 cubic inches or 160 in^3
Answer:
angle 2, 4, 6 are 34 degrees
angle 7, 5, 1, 3 are 146 degrees
180-34= 146
