First, the factor pairs for 18 are:
1, 18
2, 9
3, 6
Since the middle term is -3, the two factors must be 3 apart. The only pair that is 3 values apart is 3, 6.
Since the middle value is negative, the larger number is negative. This means that the 6 is negative.
z = -6
z = 3
Set each equal to 0;
z = -6
z + 6 = 0
z = 3
z - 3 =0
So your factors are (z+6) and (z-3), or answer B.
Answer:
-4
Step-by-step explanation:
-3-1= -4
A negative minus a positive= a "larger" positive.
Check the picture below, is a negative angle, thus, is going "clockwise"
Interest = principle * rate * time...
I = PRT...we are going to rearrange this because we are looking for the principle...
I / (RT) = P
I = 22.40
R = 2.8%...turn to a decimal = 0.028
T = 1
sub and solve
22.40 / (0.028(1) = P
22.40 / 0.028 = P
800 = P....amount of original deposit is $ 800 <==
