how do i do this? i know how to do box method for factoring polynomials but this literally killed my brain bestie pls help me

When using the box method, it's really helpful to write equations. For example in this equation, let's set the value on top of the top left box (left of the "1") as x.

So,

k * x = 5k²

Divide both sides by k

x = 5k

Set the other unknown factor (the one below "k") as y.

So,

y * 1 = -7

y = -7

Now, solve for the missing products:

k * 1 = k

5k * (-7) = -35k

I hope this helps! Feel free to ask any questions!

all but the second one

cuz that one goes over 180

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.
