What is the length of DE where EF is a median of trapezoid ABCD the length of AB is 12 and the length of CD is 18?
The median of a trapezoid is one half of the sum of the two sides. So EF is 1/2 (12+18) = 1/2 (30) = 15.
If MN equals x-1 and AB equals 6x-18 then AB equals?
4... if you plug it in, it works
The height of a triangle is four times the length of the base find the base and height of the triangle if the base is 18 square inches?
18 square inches is probably the area of the triangle, not the length of the base. The length of the base would be measured in inches (a unit of length), not square inches (a unit of area). So area = 1 / 2 * base * height = 18 square inches (given) height = 4 * base (given) 1 / 2 * base * 4 * base = 18 square inches 2 * base * base = 18 square inches base * base = 9 square inches base = 3 inches height = 4 * base = 4 * 3 inches = 12 inches Checking our work: height is 4 times the base (12 = 4 * 3) area is 18 (1/2 * 12 * 3).
Plot and connect the points A(-1, -5), B(6, -5), C(6, 2), and D(-1, 2).What is the difference between the length of BC and the length of AB?
B.2 units
Find the length of AB and the coordinates of its midpoint Point A is plotted as -2X and 3Y Point B is plotted as 5X and -4Y?
a = (-2,3)b = (5,-4)vector AB = b - a = (7,-7)Length of AB = sqrt( 72 + 72) = sqrt(98) = 7*sqrt(2)Midpoint of AB = a + (b-a/2) = (-2,3) + (7/2,-7/2)= (3/2,-1/2)
What is the length of DE where EF is a median of trapezoid ABCD the length of AB is 12 and the length of CD is 18?
The median of a trapezoid is one half of the sum of the two sides. So EF is 1/2 (12+18) = 1/2 (30) = 15.
If A (-1 -3) and B (11 -8) what is the length of ab?

What is the length of a triangle with an area of 18 square inches and a height of 12 inches?
The length of a triangle with a height of 12 inches and an area of 18 square inches is 3 inches, since area is 1/2 * base * height. Therefore, 2 * area divided by height = 2 * 18 /12 = 3
plot the given points in a coordinate plane. Then determine whether the line segments named are congruent. 1 A(0, 1), B(4, 1), C(1, 2), D(1, 6); line AB and line CD?
we can create a graph with the x-axis representing the horizontal values and the y-axis representing the vertical values. let's determine whether the line segments AB and CD are congruent. The length of line segment AB can be calculated using the distance formula: AB = sqrt((x2 - x1)^2 + (y2 - y1)^2) For AB(0, 1) and CD(4, 1), the length of AB is: AB = sqrt((4 - 0)^2 + (1 - 1)^2) = sqrt(16 + 0) = sqrt(16) = 4 For CD(1, 2) and CD(1, 6), the length of CD is: CD = sqrt((1 - 1)^2 + (6 - 2)^2) = sqrt(0 + 16) = sqrt(16) = 4 Since the length of AB is equal to the length of CD (both are 4 units), we can conclude that line segments AB and CD are congruent.
This ellipse is centered at the origin and has a horizontal axis of length 12 and a vertical axis of length 18 What is its equation?
Apexx2/36 + y2/81 = 1~PurpleLicious~
If a equals negative 1 -3 and b equals 11 -8 what is the length of AB?
If you mean endpoints of (-1, -3) and (11, -8) then the length works out as 13
What is the the formula for finding the area of a triangle?
Area of Triangle= 1/2(ab) You must multiply length b and length a together and then half it.
How is the mixed number of 18 over 12 equal 1 and 1 half?
18/12 = 12/12 + 6/12 12/12 = 1 6/12 = 1/2
If a(-1-3)and b(11-8)what is the length of ab?
If you mean endpoints (-1, -3) and (11, -8) then by using the distance formula the length between the points is 13 units
Perimeter of 18 units you are a rectangal your length is 1 unit bigger than your width What are your dimensions?
Perimeter of a rectangle is (2 x Length) + (2 x Width) (2 x length)+(2 x width) = 18 length = 1+width 2(1+w) + (2w) = 18 2+2w+2w=18 2+4w=18 4w=16 w=4 l=1+4=5 Width = 4 Length = 5
