Step-by-step explanation:
First no. is 12
Second no. is 8
Third no. of 25
Way 1 of grouping the numbers,
(12×8)×25
We can use associative law of multiplication as follows :
(a×b)×c = a×(b×c)
(12×8)×25 = (96) × 25
= 2400
Way 2,
12×(8×25) = 12 × 200
= 2400
Way 2 is easier to simplify because when we multiply 8 and 25, we get 200. It is very easy to multiply any number with a number that have zeroes. As a result we easily get the answer i.e. 2400.
You use the factor tree.

5 2 then you have 2 prime numbers and you have to multiply them together
The total displacement east is: <span>
<span>15 cos(45) + 15
= 25.607 m
The total displacement north is:
15 sin(45)
= 10.607 m
The magnitude of the total displacement is:
sqrt(25.607^2 + 10.607^2)
<span>= 27.717 m = 27.7 m</span>
Its direction is N x E where:
tan(x) = 25.607 / 10.607
<span>x = 67.5 deg
The return displacement is therefore of the same magnitude
but in the opposite direction.
<span>Displacement 27.7 m, direction S 67.5 deg W</span></span></span></span>

a parrallogram is a square of sorts, so just take the base times the height divided by two for the triangle portion than multiple by 2 to get rhe same answer back because those two triangles make a square
