Answer: a and d
Step-by-step explanation:
(to find all points of discontinuity, set denominator equal to zero and solve)

(to factor, find two numbers when added together equal -7 and when multiplied together equal 10)
-2 + -5 = -7
-2(-5) = 10
-2 and -5 are the two numbers

Answer:$13.50
Step-by-step explanation:
First thing you want to do is find what is 6% of 14.31. You can find this using your calculator and putting the percentage in decimal form then multiplying it by the given amount. 0.06 x 14.31 = ? And then you take that number and subtract it from 14.31.
Answer:
23
Step-by-step explanation:
The sides opposite equal angles of a triangle have equal length:
KJ = IJ
9x -11 = 6x -5
3x = 6 . . . . . . . . add 11-6x
x = 2
__
Perimeter = (7x-5) +(6x -5) +(9x -11) = 22x -21 = 22(2) -21 = 23
The perimeter of triangle JIK is 23 units.
