If Z is the midpoint of XY then .?
Z is halfway between X and Y.
Factor this Expression xz plus x plus yz plus y?
xz + x + yz + y = (x + y)(z + 1)
What is the distributive property of multiplication over addition?
The distributive law of multiplication over addition says that if x, y and z are any numbers, then x(y+z) = xy + xz . It's true not only for integers, but also for real numbers or even complex numbers. Here's a proof / graphical explanation: __________ |*****|***| ^ |*****|***| | |*****|***| |x |*****|***| | |*****|***| v --------------- <--y--><-z-> Consider the ASCII rectangle above. It has height x and width y+z, therefore its area is x(y+z). Alternatively, it can be viewed as two smaller rectangles joined together. The one on the left has height x and width y, so its area is xy. Similarly, the one on the right has area xz. So the total area is xy + xz. Therefore x(y+z) = xy + xz.
What are the three angles in triangle xyz when xy equals 3.4 cm yz equals 5.2 cm and xz equals 4.9 cm?
Using the cosine rule the three angles are as follows:- x = 75.16700977 = 75o 10' 1.24'' y = 65.6309069 = 65o 37' 51.26'' z = 39.20208333 = 39o 12' 7.5''
If Z is the midpoint of and XY and W lies on as shown below which of the following expressions are also true?
Zw < xyyw + wz = yzwy + wz = xz
