Answer:
2.56
Step-by-step explanation:
Monday: 2 * 2.21 = 4.42
Tuesday: 4.42 + 0.39 = 4.81
Wednesday: 4.81 - 1.76 = 3.05
Thursday: 3.05 - 1/5 * 3.05 = 3.05 - 0.61 = 2.44
Friday: 2.44 + 0.12 = 2.56
These already are reduced using a greatest common factor
The answer is for (6x^2-6x-5)(7x^2+6x-5) is B
4 × ( x + 4 ) = 3 × ( 3 + 5 )
4 × ( x + 4 ) = 3 × 8
Divide both sides by 4
x + 4 = 3 × 2
x + 4 = 6
Subtract both sides 4
x = 2
