What is the perimeter and area of a equalateral triangle whoose base 6m and height is 4m?
This is not an equilateral triangle if height is 4 m the base is 6 m and by Pythagorean theorem the other sides are 5 m perimeter is 6 + 5 + 5 = 16m Area = base x height = 6 x 4 = 24 sq m
What is the equation of a line that passes through the poin -2-4 and -7-1?
(- 2, - 4) and (- 7, - 1)First the slope is needed.m = Y2 - Y1/X2 - X1m = - 1 - (- 4)/- 7 - (- 2)m = - 3/5==========now, point slope form, use these points (- 2, - 4)Y - Y1 = m(X - X1)Y - (- 4) = -3/5[X - (- 2)]Y + 4 = - 3/5(X + 2)Y + 4 = (- 3/5)X - 6/5Y = (- 3/5)X - 26/5===============equation of the line
What is perimeter of a square with 1.25m sides?
Square has 4 sides, so 4 x 1.25 = 5 m
What are the possible dimensions for the length and the width for a rectangle that has a perimeter of 12 meters if each side is a whole number of meters?
The perimeter of a rectangle is twice the length plus twice the width so half the perimeter is the length plus the width. If the perimeter is 12 m, then the length plus the width must equal 6. The dimensions could therefore be 1 m x 5 m, 2 m x 4 m, 3 m x 3 m (although this would be a square), 4 m x 2 m or 5 m x 1 m.
What is the value of 5m2 plus 4n2 if m equals 4 and n equals 3?
5 x 16 + 4 x 9 = 80 + 36 = 116
