Answer:
Step-by-step explanation:
Δy =-4-1 = -5
Δx =-8-(-6) = -2
distance = √((Δx)^2+(Δy)^2) = √(4+25) = √29
You could give all of the fractions a common denominator. You could also solve each of them (1/2=0.5) to see their value and order them through the value.
Answer:
4x - 4y - 7z
Step-by-step explanation:
x - 3y + 4z + y - 2x - 8z + 5x - 2y - 3z =
(x - 2x + 5x) + (y - 3y - 2y) + (4z - 8z - 3z) =
4x + (- 4y) + (-7z) =
4x - 4y - 7z <===
Answer:
I could be mistaken but I believe that x= 42.5
Step-by-step explanation:
To find this, you solve for 4x+10=180.
This is because the total angle measure of line RD should be 180 degrees.
When you solve this equation, you get 42.5 for X
Volume = 1/3 pi r^2 h
= 1/3 * 10^2 *81 pi
= 2700 pi units^3
