d. −2u − 3(5v − 3w)
e. ‖u‖, ‖v‖ and ‖w‖
f. show that ‖v‖ = ‖‖.
g. show that ‖u + v‖ ≠ ‖u‖ + ‖v‖.
h. show that ‖v − w‖ ≠ ‖v‖ − ‖w‖.
i.
‖u‖ u and
‖u‖

answer: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

11

step-by-step explanation:

32.50-7.50=25

225/25=11

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
