Answer:
The value of x is 12
Step-by-step explanation:
To find the value of x, we need to note that the interior angles are equal to 180. We also know that angle R is equal to 180 - (8 + 6x). So we can add all of this together and set equal to 180.
180 - (8 + 6x) + 4x + 2 + 30 = 180
180 - 8 - 6x + 4x + 2 + 30 = 180
-2x + 24 = 0
-2x = -24
x = 12
Answer: 1.4 or 1 2/5
Reason: if you were to do 8.4÷6 you would get 1.4 and to check your work you can do 1.4×6 which is 8.4 or 8 2/5

Answer: Choice C is correct</h3>
Explanation:
We can think of the square in the middle of the four others as the floor
The surrounding four squares are the walls that fold upward.
The square at the very right side will then form the ceiling.
Side E and side L join at the top left edge.
See the diagram below.
In general, to find the surface area of a prism (a shape with 2 bases) is
Area of Base*2 + Lateral Area (Lateral area = Perimeter of bases * height)
#9 Area of base= 2×1÷2=1 *2=2
Lateral area= 2+1+2.2=5.2 5.2*3=15.6
Answer=17.6
#10 Area of Base= 120*2=240
Lateral Area=500
Answer=740
#11
Area of base=8*2=16
Lateral Area= 41.4
Answer=57.4
Answer:
option a
Step-by-step explanation:
95 +x=180
x=180-95=85
85+31+y=180
116+y=180
y=180-116=64
