Distributive Property

Step-by-step explanation:

The distributive property essentially states that any expression in the form of a × (b + c), the operand, "a" distributes over addition or subtraction through multiplication.  Thus, distributing -7 into (w - 4) results in -7w + 28 on the left-hand side of the equation.

-7w + 28 - 28 = 49 - 28  → Subtraction Property of Equality

-7w = 21  →  Division Property of Equality          

 → Simplify  

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
