Please help me !!!( the directions for the top is to factor the following difference of squares. Check your answers by FOIL. The bottom math problems have directions at the top of it ) Answer what you can correctly for a brainliest and also get a thanks ! Don't answer if you don't know it .

I'm very disappointed and a little depressed that you can't do any of these twenty problems on your own, and you decided to just dump them on Brainly. I'm also disappointed that yuu thought the whole thing is only worth 11 points.
I'll do a substantial amount of each problem, but not all of it. Some of the contribution should be yours.
This whole page is just a bunch of exercises for one fact:
(any difference of two squares) is equal to
(the sum of the square roots of the terms) times (the difference of the square roots of the terms) .
That's the solution to everything on the page, right there.
For this second group, I confess that I did them all in my head, so you should really do some checking just to make sure.
You are working as a clinical chemist in charge of the testing of blood samples. You are required to mix a solution of sodium chloride with water in the ratio of 2:5. Starting with 780ml of the sodium chloride solution, how much water needs to be added? Give your answer in standard form to an appropriate number of significant figures.
Answers
1,950 ml of water should be added to 780 ml of sodium chloride to maintain the ratio of 2:5
Given: Ratio of sodium chloride to water 2:5 sodium chloride = 780 ml water = ?
proportionality a:b = c:d where ad = bc
a = 2 ; b = 5 ; c = 780 ml ; d = x
2:5 = 780:x 2x = 780*5 2x = 3900 x = 3900/2 x = 1950 ml of water.
darcy likes to eat peanut butter and raisins on apple slices. on each apple slice she puts 1/16 cup of peanut butter and 8 raisine.Darcy has 2/5 cup of peanut butter and 80 raisins . She eats a whole number of apple slice until the peanut butter is all gone . what fraction of the 80 raisins did she eat ?
Answers
The answer is 7/10.
For one apple slice, Darcy needs 1/16 cup of peanut butter and 8 raisins. She has 2/5 cup of peanut butter. To compare how many butter she has and she needs we will divide 2/5 with 1/1
This means that Darcy needs 5/80 cup of peanut butter and 8 raisins. If she has 32/80 cup of peanut butter, she will have it only fo 6 or 7 apple slices (32/80 ÷ 5/80 = 6.4) depending how it is rounded. If she prepares 6 apple slices, she will still have a little of peanut butter left (0.4 = 2/5 of cup). So, she will prepare 7 apple slices so the butter will be all gone.
For 7 apple slices, she needs 56 raisins (7 × 8 raisins). That is 56 raisins out of 80 raisins, so fraction of the 80 raisins did she eat is:
