Show work to all the questions! ill five brainliest answer! 1.what is the solution to x2 + 3x + 25 = 0? use quadratic formula2.what are the zeroes of y = x2 + 14x +40 3.what is the solution to the following equation? x2 + 7x – 18 = 0

1 : complex # : [ - 3 ± i√91 ] / 2 

2 y = [ x + 7 ]² - 9 ---> x = 3 ± 7

3 x^2 - 7x - 18 = 0
x^2 - 9x + 2x - 18 = 0
x(x - 9) + 2(x - 9) = 0
(x - 9)(x + 2) = 0
x = -2
x = 9

I hope that helps I honestly suck at algebra anymore

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
