Answer:
Step-by-step explanation:
Question 1: C
1 multiplied by 5 = 5
1 plus 5 = 6
So you get: (x+5)(x+1) which means x = -5 or -1
Question 2: B
2 multiplied by -4 = - 8
2 plus -4 = -2
So you get: (x-4)(x+2) which means x = 4 or -2

Answer:
Step-by-step explanation:
If y=6 and z=3, then plug in the numbers given to the variables.
3/2 times 6, -3 + 5/3 times 3.
6= 6/1, so, you can do the same operation.
3/2 times 6/1. then subtract 3 from that.( you have to simplify them to make equal denominators)
5/3 times 3/1 then add that to your previous answer.
