Answer:
The answer to your question is b, c and d
Step-by-step explanation:
Equation given
3m = 36 - 6m
3m + 6m = 36
9m = 36
m = 36/9
m = 4
Equation a
-1/3 m + 2 = -1
-1/3 m = -1 - 2
-1/3 m = -3
m = -3 x -3
m = 9
Equation b
-2(-4m - 6.4) = 44.8
-4m - 6.4 = 44.8/-2
-4m = -22.4 + 6.4
-4m = -16
m = -16/-4
m = 4
Equation c
8m - 5 - 2m + 1 = 20
6m = 20 + 4
6m = 24
m = 24/6
m = 4
Equation d
7m + 6 = 9m - 2
7m - 9m = -2 - 6
- 2m = -8
m = -8/-2
m = 4
Answer:
B, C and D.
Step-by-step explanation:
3m=36-6m
9m=36
m=4
-1/3m+2=-1
-1/3m=-3
m=9
So not it
B, c and d is the same as they all equal to 4.

Answer: 455 different ways (15 x 14 x 13) / (3 x 2 x 1) = 455
We have that
[the area of the trapezoid]=[area of rectangle]+2*[area of triangle]
[the area of the trapezoid]=[10*9]+2*[9*9/2]
[the area of the trapezoid]=[90]+2*[40.5]= 171 units²
see the attached figure
the answer is 171 units²
