(- 8, - 7) and (- 5, - 5)Need slope first. m = Y2 - Y1/X2 - X1m = - 5 - ( - 7)/- 5 - (- 8)m = 2/3========Now, I use point slope form to get us half way thereY - Y1 =m(X - X1) ( - 8, - 7) points usedY - (- 7) = 2/3[X - (- 8)Y + 7 = 2/3(X + 8)Y + 7 = (2/3)X + 16/37 = 21/3, soY + 21/3 = (2/3)X + 16/3Y = (2/3)X - 5/3===========================standard form
If one side is 8 m then the side opposite is also 8 m. Similarly if the adjacent side is 3 m then the side opposite that is also 3 m. thus the perimeter = 8+3+8+3 m = 22m.
5+3=8 3+5=8 8-3=5 8-5=3
m + 3 - 20 = 5 m + 3 = 25 m = 22
If 3m - 7 = 8, then m = 5
8
If you want to find the perimeter of a shape, just add up the lengths of all the sides. 6 + 8 + 8 + 5 + 2 + 3 = 32 metres
(15/m) - m + 8 = 1015/m - m = 215 - m2 - 2m = 0 or m2 +2m - 15 = 0This factoises as (m +5)( m - 3), so m = 3 or -5
Displacement vector in the same direction = 3 m + 5 m = 8 m.
8 km is longer then 8 m as 5 m then 5 mm
m/8 - 10/5 = m/8 - 2
(- 2, 15) and (- 8, - 5)m = Y2 - Y1/X2 - X1m = - 5 - 15/- 8 - (- 2)m = 10/3=======
Volume = 1/3 * h * Base Area of Pyramid = 1/3*8*(5*3.6) = 1/3*8*18 = 48 m3 Use google next time.
m/5 + 8 = -7 m/5 = -15 m = -15 x 5 m = -75
