Answer:
The equivalent expression is 3x^5-9x^3-2
Step-by-step explanation:
To find the equivalent expression, we need to
open up the brackets;
Thus;
x^2(3x^3 -2x) - (7x^3 + 2)
= 3x^5 -2x^3 -7x^3 -2
= 3x^5 -9x^3-2
2.40/12 = x/16
then that would mean 12x= 2.40(16)
which equals 12x= 38.4, then divide 12 by both sides, getting you 3.2 so the answer is it would cost her $3.20 cents to by 16 lemons
Answer:
P = x³ − 9x² + 36x − 54
Step-by-step explanation:
Complex roots come in conjugate pairs. So if 3−3i is a zero, then 3+3i is also a zero.
P = (x − 3) (x − (3−3i)) (x − (3+3i))
P = (x − 3) (x − 3 + 3i) (x − 3 − 3i)
P = (x − 3) ((x − 3)² − (3i)²)
P = (x − 3) ((x − 3)² + 9)
P = (x − 3)³ + 9 (x − 3)
P = x³ − 9x² + 27x − 27 + 9x − 27
P = x³ − 9x² + 36x − 54
Answer:
165
Step-by-step explanation:
5% of 150 british pounds = 7.5 British pounds
2 years = 7.5 BS per year
7.5 + 7.5
= 15 british pounds
15 british pounds + 150 british pounds =
165 british pounds
