When you subtract a negative it is same as just adding the number so 3x--19=3x+19
You now have 3x+19=11
Subtract both sides by 19 and you get 3x=-8
Divide by 3 and you get x=-8/3 which is -2 and 5/3 or -2.667
Answer:
a) 3x(y-3)
b) (x-2)(X+2)

Answer:
12.5 square inches
Step-by-step explanation:
The area of the base can be written as ...
B = LW
Then the volume formula ...
V = LWH
can be written in terms of the base area as ...
V = BH
The base area can be found by dividing by the height:
B = V/H = (50 in³)/(4 in) = 12.5 in²
The area of the base is 12.5 square inches.
