I think its not a correct solution of given equations.
u - v = <5, 2> - <2, - 3> = <5 - 2, 2 + 3> = <3, 5>
given a vector <u, v> then the magnitude is √ (u² + v² ) and it's angle of direction is
θ =
(
)
thus the magnitude of <3, 5> = √(3² + 5²) = √34 ≈ 5.83 ( to 2 dec. places )
Θ =
(
) = 59.04° ( to 2 dec. places )

Area of the figure is 102 cm²
Step-by-step explanation:
- Step 1: Find the area of the square with side = 6 cm.
Area of the square = (side)² = 6² = 36 cm²
- Step 2: Find the area of the trapezoid.
Length of parallel side 1 = 7 cm
Length of parallel side 2 = 21 - 6 = 15 cm
Height = 6 cm
⇒ Area of the trapezoid = 1/2 × (Sum of parallel sides) × height
= 1/2 × (7 + 15) × 6
= 1/2 × 22 × 6 = 66 cm²
- Step 3: Find the area of the figure.
Area of the figure = Area of the square + Area of the trapezoid
= 36 + 66 = 102 cm²
Given:
Bella bought packs of stickers to give to her friends.
Cost of each pack of stickers = $4
Total amount spent on packs of stickers = $12
To find:
The equation for the given statement.
Solution:
Let s be the number of packs of stickers.
Cost of one pack of stickers = $4
Cost of s packs of stickers = $4s
Total amount spent on packs of stickers is $12. So,

Therefore, the correct option is B.
