Answer:
48
Step-by-step explanation:
u • w
= (i + 6j ) • (9i - 2j )
= (1 × 9 ) + (6 × - 2 )
= 9 + (- 12)
= 9 - 12
= - 3
v • w
= (5i - 3j ) • (9i - 2j )
= (5 × 9) + (- 3 × - 2)
= 45 + 6
= 51
Then
u • w + v • w
= - 3 + 51
= 48
Answer:
the constant of proportionality would be 9

- Formula For Area Of Trapezoid:
-----------------------------------------
A = 10
B = 18
H = 6
- Plug Numbers Into Equation:
10 + 18 = 28
28 ÷ 2 = 14
14 · 6 = 84
