Answer:
None of the answers are right
Step-by-step explanation:
Since a hexagon has 6 sides, and perimeter is the length of all the sides summed up, we can multiply 6 by 2x+y to find the perimeter.
6(2x+y)
Distribute the 6 to each term in the parentheses:
6(2x)+6(y)
12x+6y is the perimeter. None of the answers are right.
As an improper fraction, it would be -11/4
As a mixed number, it would be
-2 and 3/4
Answer:
x=1
Step-by-step explanation:
So, first you make sure to multiply the parenthesis by the negative so then it would be,
-x-3=2x-6
Then you add the -3 from the right to the other side
so, -x=2x-3
Then you want all the X variables to one side so you subtract the 2x to both sides.
so, -3x=-3
divide both by -3
x=1
-4 isn't a real number because there is no square root of -4. However, there is a cube root of -8, because -2 * -2 * -2 = -8.
Answer:
The number is 7.
Step-by-step explanation:
The unknown number: x
9 (x + 7) = 126
Using the distributive property, 9x + 63 = 126
9x = 63
x = 7
