Answer:
Step-by-step explanation:
hello :
the system is : x+ y =4 ...(*)
2x - y = -1...(**)
add(*) and (**) : 3x=3 so : x=1
put this value into (*) : 1+y=4 so : y=3
one solution : (1 , 3)
Answer:
V = x³ + 20x² + 124x + 240
Step-by-step explanation:
Volume of a rectangular prism is width times length times height.
V = wlh
Given w = x+4, l = x+10, and h = x + 6:
V = (x + 4)(x + 10)(x + 6)
V = (x + 4)(x² + 16x + 60)
V = x²(x + 4) + 16x(x + 4) + 60(x + 4)
V = x³ + 4x² + 16x² + 64x + 60x + 240
V = x³ + 20x² + 124x + 240
