#1
Area of base=1/2(2.8)(4.2)
Volume:
- Area of base×Height
- 5.88(7)
- 41.16in³
#2
Area of base
- 6×1/2(7)(6.1)
- 3(7)(6.1)
- 128.1cm²
Volume:-
5x-2x+6x+40-9+1-x+3x-8+15+7
First you would combine like terms:
5x - 2x + 6x - x + 3x = 11x and
40 - 9 + 1 - 8 + 15 + 7 = 46, so the simplified expression would be
11x + 46
Letting

, we get

and

, so we can parameterize the intersection by

where
