Answer:
A. h = 4
B. g = 15
C. b = -6
D. b = 15
Step-by-step explanation:
A. 9h + 8 - 12 = -40
9h - 4 = -40
+ 4 + 4
9h = -36

h = -4
B. 9 + 6g + 1 = 100
10 + 6g = 100
- 10 - 10
6g = 90

g = 15
C. -45 = 28 - 13 + 10b
-45 = 15 + 10b
- 15 - 15
-60 = 10b

b = -6
D. 37 = 11 +3b - 19
37 = 3b - 8
+ 8 + 8
45 = 3b

15 = b
Surface area is the area of a base so:
We have to mulityply the height by the length to find the answer so the answer would be 4x6 which is 24square cm hope this helps!

Answer:
the system of equation has infinite solution
Step-by-step explanation:
, 
Solve the first equation for x_2
Subtract 5x1 on both sides


Now substitute -5x1 on second equation



0=0
So the system of equation has infinite solution
