Answer: D
Step-by-step explanation:
dim A=(a,b), dim B=(c,d), in order to multiply, c=b
1) dim A=(1,2) , dim B=(1,2) but 2≠1
2) dim A=(2,1) , dim B=(2,2) but 1≠2
3) dim A=(2,2) , dim B=(1,2) but 2≠1
4) dim A=(2,1) , dim B=(1,2) 1=1: result (2,2)
A= -2
B= 4
C= -3
The equation the help you with this for later reference is **ax^2 + bx + c=0**
147 =20x+47
147 is less than or equal to 20 multiplied by the number of hours she works (x) plus 47 the amount of money she already has
