I use simple annual interest to solve the problem

<span>$125.37 -------------------------------- 3 years
X-------------------------------------------> 1 year
X=125.37/3=</span>$41.79/ year

<span>$597--------------------->100%
</span>$41.79---------------------X%

X=41.79*100/597=7%
The rate was 7%

Solve for all values of x by factoring.<br> x^2 + 4x – 30 = -3x

vichka [17]

Answer:

${x}^{2} + 4x - 30 = - 3x \\{x}^{2} + 7x - 30 = 0 \\ {x}^{2} - 3x + 10x - 30 = 0 \\ x(x - 3) + 10(x - 3) = 0 \\ (x - 3)(x + 10) = 0 \\ \boxed{x = 3} \\ \boxed{x = - 10}$

<h3><em><u>x=3 or x=-10</u></em> is the right answer.</h3>

The sum of the numbers from 1 to n can be performed recursively as follows: The sum from 1 to 1 is 1. The sum from 1 to n is n m

pogonyaev

Answer:

S(1) = 1

S(n) = S(n-1) + n

Where S(n) is the sum from 1 till n

And,

S(n-1) is the sum from 1 till n-1
