Answer:
The correct answer is option B.
5x⁵ + -8x³ + x² + 5x -1
Step-by-step explanation:
It is given that,
(x³ + 2x⁴ + 5x⁵ - 2x - 1) - (-7x - x² + 9x³ + 2x⁴)
<u>To find the subtraction result</u>
(x³ + 2x⁴ + 5x⁵ - 2x - 1) - (-7x - x² + 9x³ + 2x⁴)
= x³ + 2x⁴ + 5x⁵ - 2x - 1 + 7x + x² - 9x³ - 2x⁴)
= 5x⁵ + 2x⁴ - 2x⁴ + x³ - 9x³ + x²- 2x + 7x -1
= 5x⁵ + -8x³ + x² + 5x -1
The correct answer is option B.
5x⁵ + -8x³ + x² + 5x -1
Answer: 5
Explanation: This type of algebraic expression is called a power.
Here, 2 represents the base and the represents the <em>exponent</em>.
The remaining balances in the first and second account are $5805 and $1020 respectively.
<em><u>Explanation</u></em>
Suppose, the initial balance in the first account was
dollar.
As the total amount in two accounts was $9000, so the <u>initial balance in the second account was</u> 
He withdrew 10% from the first and 60% from the second account to buy the ring which cost $2175. So, the equation will be......

So, <u>the initial balance</u> in the first account was $6450 and in the second account was ($9000 - $6450)= $2550
Thus, the remaining balance in the first account = 90% of $6450 =
and the remaining balance in the second account = 40% of $2550 =
