Answer:
-9,-21
Step-by-step explanation:
let the numbers be x and y and x>y
x-y=12
y=2x-3
x-(2x-3)=12
x-2x+3=12
-x=12-3
-x=9
x=-9
y=2(-9)-3=-18-3=-21
Answer: A
solve the first equation for y
4x + y = -12
subtract both sides by 4x
y = -4x - 12

Step-by-step explanation:
<u>Sides of the prism:</u>
- 2*1/3 = 2/3 ft
- 3*1/3 = 1 ft
- 5*1/3 = 5/3 ft
<u>Volume:</u>
- 2/3*1*5/3 = 10/9 = 1 1/9 ft³
