X=8 and x=18 the absolute value equation that has a given solution i dont get this can you show me step by step how to solve this

Ok so x=8, 18 are the zeroes or solutions for the given equation you will put this into a for called x-intercept form

(x-a)(x-b)=c

let c be 0 so when you find the Xs you can get the solutions (ex. x-8=0 => x=8)

I am not sure what answer you wanted but here is how to get to the original equation

1) multiply the binomials =>

2) you will get

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
