I think it's the first choice. T and F = F. hope this helps :D
Let the volume of prism A be X. Then the volume of prism B is 2X. The combined volume could be described like this:
432 = X + 2X
Solving the equation,
432 = 3X
432/3=X
144=X
The volume of A is 144 cubic feet, while the volume of B is 288 cubic feet.
Answer:
B (6 , 0)
Step-by-step explanation:
(2,8) Add 2 to x-axis and subtract 1 from y-axis
(4,1)
(6,0)
The answer is ‘y=30’
i don’t really know how to explain it but multiply the first top number’-4x’ with all of the bottom numbers. Multiply the first number at the bottom ‘-10’ by all the numbers at the top.
-40x-20y=-140
-40x+28y=-100
