Answer:
x = -7
Step-by-step explanation:
First, you must distribute the -3 to the numbers in the parenthesis. You will get -18x - 6. the problem is now 113 = x - 18x - 6. With inverse operations this will become 119 = -17x. Divide 119 by -17 and you will get -7. x = -7.
Answer:
94°
Step-by-step explanation:
This is a quadrelateral, and so all the sides must equal 360.
Set the equation: F + 66 + 132 + 68 = 360
Isolate the variable F. First, simplify. Combine like terms: F + (266) = 360
Isolate the variable F. Subtract 266 from both sides:
F + 266 (-266) = 360 (-266)
F = 360 - 266
F = 94
94 is your answer.

Step-by-step explanation:
Answer:
The perimeter of the regular octagon is 104 units
Step-by-step explanation:
we know that
The segment LM is the length of one side of the octagon
we have the coordinates
L(-6,-2) and M(6,3)
step 1
Find the distance LM
the formula to calculate the distance between two points is equal to
substitute the values
step 2
Find the perimeter
we know that
A regular octagon has eight equal sides
so
To find out the perimeter, multiply by 8 the length of the segment LM
