Six multiplied by three equals eighteen. fifteen plus three equals eighteen. and eighteen equals eighteen. therefore the equation is equal, because everything in the equation equals eighteen. Good Luck ;)
Answer:
Simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .
Step-by-step explanation:
As the expression given in the question be as follow .
= (x−3)( x²−4x−7)
simplify the above
= x (x²-4x-7)-3 (x²-4x-7)
Now open the bracket
= x³ - 4x² -7x - 3x² + 12x + 21
= x³- 4x²-3x²-7x + 12x + 21
= x³ -7x² + 5x + 21
Thus the simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .
Answer:
8x/5
Step-by-step explanation:
Question 1
Pv=pmt [(1-(1+I)^(-n))÷I]
Pv=256×((1−(1+0.021)^(−29))÷(0.021))
pv=5,518.198
Question 2
PMT=pv÷[(1-(1+I)^(-n))÷I]
PMT=19,621÷((1−(1+0.023)^(
−77))÷(0.023))
=546.09
Question 3
N=log ((1-((pv×I)÷pmt))^(-1))÷log (1+I)
N=log((1−(14,000×0.015)
÷450)^(−1))÷log(1+0.015)
=42.22years
