Can you take the quantity [ x + y ] and square it ?
Can you take the quantity [ x + 2y ] and square it ?
Then you should have no trouble with the square of (.9x + .8y) .
The square of any binomial (expression with 2 terms) is
(square of the first term)
+ (square of the second term)
+ 2 times (product of the terms) .

Answer:
V ( Vcos 60° , Vsin60°) or V ( 2, 2√3)
Step-by-step explanation:
A vector and its components form a right triangle, then we need to get trigonometric functions ( sin and cos) of the angle of the module with x-axis
π/3 = 180⁰/3 = 60⁰ Angle between vector and positive x-axis
and sin 60⁰ = √3 /2 cos 60⁰ = 1/2
Let call V(x) component of vector v in x-axis, and V(y) component of vector v in y-axis then
V(x) = |v|*cos 60⁰ ⇒ V(x) = |v|*1/2 ⇒ V(x) = 4*1/2 ⇒ V(x) = 2
And
V(y) = |v|*sin 60⁰ ⇒ V(y) = |v|*√3/2 ⇒ V(y) = 4*√3/2 V(y) = 2*√3
V = (Vx,Vy) V ( Vcos 60° , Vsin60°) V ( 2, 2√3)
Answer:
(4 × 3) × 6 = 4 × (3 × 6) shows the Associative Property of Multiplication.
All parallel lines have the same slope. So the product of the slopes of line AB n a line parallel to AB is m*m=m^2
