Answer:
Step-by-step explanation:
The diameter is twice the radius, so ...
XY = 2·ZY
12x -4 = 2(3x +4) . . . . substitute the given expressions
12x -4 = 6x +8 . . . . . . eliminate parentheses
6x = 12 . . . . . . . . . . . . add 4-6x
x = 2
YZ = 3x+4 = 3(2) +4
YZ = 10
Answer:8m^2n - 32m^2 + 15n^2 - 18mn^2
Step-by-step explanation:
4m x 2mn = 8m^2n
4m x -8m = -32m^2
3n x 5n = 15n^2
3n x -6mn = -18 mn^2
when you add them all together,
8m^2n - 32m^2 + 15n^2 - 18mn^2
