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 .

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.
OK. Here we go:
15). (2c + √5 d) (2c - √5 d)
16). (7m² + 4) (7m² - 4)
17). (k³ + 4) (k³ - 4)
18). (2p² + 5) (2p² - 6)
19). (11r³ + 1) (11r³ - 1)
20). (8m² + 3n) (8m² - 3n)
You can do the FOIL checking. I buried one error in there
just so that you'd have something to look for and fix.
21). 6 (2a + 3b) (2a - 3b)
22). 9x (2x + 1) (2x - 1)
23). 5q (3q + 2) (3q - 2)
24). 2 (4s + 3u) (4s - 3u)
25). 4b (5b + 3) (5b - 3)
26). 3x² (x² + 4) (x² - 4)
27). 8y (x + 2y) (x - 2y)
28). 5m (5m + 1) (5m - 1)
29). 3 (n + 7) (n - 7)
30). 2 (3x + 5) (3x - 5)
31). m n (m + 1) (m - 1)
32). 4x (2x + 5) (2x - 5)
33). 5n² (4n + 5) (4n - 5)
34). 3 (2n + 1) (2n - 1)
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.

The density of the liquid will be 1500 kg per cubic meter.
What is density?
The density is the ratio of mass to volume of any substance.
Let m be the mass of the object and v be the volume of the object.
Then the density D will be
D = m / v kg / cubic m
More the density means the number of the molecules will be more in a unit volume.
A sample of liquid has a mass of 24g and a volume of 16ml.
We know that one kg equals to 1000 grams.
24 g = 0.024 kg
We know that one ml equal to 10⁻⁶ cubic meters.
16 ml = 16 × 10⁻⁶ cubic meters
Then the density of the liquid will be
Density = 0.024 / 16 × 10⁻⁶
Density = 1500 kg per cubic meter
Thus, the density of the liquid will be 1500 kg per cubic meter.
More about the density link is given below.

so,
24g/16ml = 1.5g per cm^3
1mL = 1cm^3
