Answer:
Step-by-step explanation:
Cross multiply on both sides
= (x + 1) (21) = 15(x + 3)
= 21x + 21 = 15x + 45
Bringing like terms on one side
21x - 15x = 45 - 21
= 6x = 24
x = 24/6 = 4
Option A is the correct answer
Please, use " ^ " to denote exponentiation: x^2 + 4x - 21 = 0
Factor: (x+7)(x-3)=0
Solve for the 2 roots: x= -7 and x= 3: {3, -7} Note how this is in set notation.

Determine the cost of 1000 bushels
If 1 bushel costs $9.79,
Then 1000 costs:


The money can be withdrawn from the account every two months for the next 6 years is $20, 625, 000
<h3>What is compound interest?</h3>
The formula for compound interest is given as;

P = principal interest = $25, 000
r = rate = 4. 5%
n = 2 months
t = 6 years
A = 
A = 
A = 
A = $20, 625, 000
Thus, the money can be withdrawn from the account every two months for the next 6 years is $20, 625, 000
