<span>3a4-2a2+5a-10)-(2a4+4a2+5a-2) 
remove first set of parentheses:
 
apply "-" sign to second parentheses (distributive prop):
 
the - of a - becomes a + :
 
combine like terms:
 

Factor out the variables that are alike:

{(1)a^4 + (-6)a^2 + 0a + (-8)}}} 
0a is just 0, makea the "a" term go away:
 
can try to factor as squares, but it doesn't work out:
8 = (-4) x (+2) product factors cannot add to make 6. </span>

Help! Find m^KNL.<br> A. 264<br> B. 196<br> C. 184<br> D. 247
Misha Larkins [42]

Answer:

  A.  264

Step-by-step explanation:

First, we have to find the value of x. Then we can use that to find the required arc measure.

∠M = (1/2)(arc KN - arc LN)

60 = (1/2)((18x -6) -(5x +17)) = (1/2)(13x -23) . . . . substitute and simplify

120 = 13x -23 . . . . . . . multiply by 2

143 = 13x . . . . . . . . . . add 23

11 = x . . . . . . . . . . . . . . divide by 13

__

arc KNL = (arc KN) + (arc NL) = (18x -6) +(5x +17) = 23x +11

  = 23·11 +11

arc KNL = 264 . . . . degrees

How to solve Question 3(c)?
BARSIC [14]
From your work on parts (a) and (b), you know that
.. r = 3.50
.. s = 140
The composite index of production cost from 2007 to 2009 is 114.2.

(c) If the production cost in 2007 was RM50, then in 2011 it was
.. RM50 * (2009 index) * (2011 index) = RM50 * 1.142 * 1.200 = RM68.52
