Answer:
X = -5
Step-by-step explanation:
-6x + 18 = 7 - (4x + 9)
first we simplify the parentheses.
distribute the invisible number one created by the negative sign in front of the parentheses to get -6x + 18 = 7 - 4x - 9
then simplify further by subtracting 9 from the right side, leaving you with
-6x + 18 = -2 - 4x
next, add 2 to both sides to isolate the variable.
-6x + 20 = -4x
then, to isolate the variable further add 6x to both sides.
20 = -4x
divide both sides by -4 to isolate the variable
-5 = x
so, x = -5
Answer:
76 and 34
Step-by-step explanation:
See attached
As we see this is a polygon with sides of AB=BC=AE and CD=DE
- Sides AB=BC=AE equal to 8
- Sides CD=DE =
= 5
Area is the sum of areas of a square ABCE with side 8 and a triangle CDE with base of 8 and height of 3:
- Area = 8*8 + 1/2*8*3 = 64 + 12 = 76
- Perimeter = 8*3 + 5*2 = 24 + 10 = 34
