Dividing 4x by 4 isolates x on one side of the equation
First need to find the length of line LJ
Line LJ = 8sqrt2 * sin(30) = 5.6569
now use that to find x
x = 5.6569 * sin(45) = 4
Step-by-step explanation:
= 2x - 9y + 4x + 11y
First of all combining like terms
So
= 2x + 4x - 9y + 11y
= 6x + 2y
Now putting values
= 6 (-2) + 2(4)
= - 12 + 8
= - 4
The answer is D. First, it is the segment addition postulate because the two segments make up the whole. Second, it's substitution because you are substituting EF + FG for FH.
Hope this helps!
