Answer:
18
Step-by-step explanation:
3 × 3/5 = 9/5
9/5 = x/10
x = (9 × 10) ÷ 5
x = 18

Answer:
The expression x² + 8x + 7 can be factored out as (x + 7)(x + 1).
Step-by-step explanation:
You can see how this factors by looking at the last term, and the coefficient of the second term. You need to find two numbers that multiply to make seven, and add to make eight.
Because seven is a prime number, this becomes very easy. If this works at all, the numbers must be seven and one.
And lo, if you check, seven and one do indeed add up to be eight, so that's what we need to use. Let's do it:
x² + 8x + 7
= x² + x + 7x + 7
= x(x + 1) + 7(x + 1)
= (x + 7)(x + 1)
Without including other expenses and the benefit of the insurance company, the premium has to meet this proportion:
1/400 = premim / value of the car
=> 1/400 = premum / $16,000
=> premium = $16,000 * (1/400) = $ 40
As already said this is witout taking into consideration the other expenses of the insurance company and their margin.
Answer: option B. $40.
The money can be withdrawn from the account every two months for the next 6 years is $20, 625, 000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Thus, the money can be withdrawn from the account every two months for the next 6 years is $20, 625, 000
