What is the value of x? enter your answer in the box. x =

this problem has only trivial solutions, with all points on the same line. x=5 or x=7/5.

Step-by-step explanation:

There are three triangles, and three unknowns: x, y=length of middle segment, and z=cos(angles marked with red arc).

We need

and law of cosines,

The three equations are

See attached image for solution.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
