Answer:
The last choice is the correct one

Explanation:
We can solve this question using "difference between squares" which has the following general rule:
a^2 - b^2 = (a+b)(a-b)

For the given question:
p^4 - 16 = (p^2 - 4)(p^2 + 4)

Now, p^2 - 4 can be further factorized using difference between squares, therefore:
p^4 - 16 = (p-2)(p+2)(p^2 + 4)

Hope this helps :)

Answer: There are 5 grasshoppers, 15 crickets and 20 ladybugs

Step-by-step explanation:

The question in english is:

Jose has found several insects. There are 10 less grasshoppers than crickets. There are 5 less crickets than ladybugs. If Jose has found 5 grasshoppers, how many ladybugs did he find and how many crickets? Write two equations to solve the problem.

Let's tag grasshoppers with $g$ , crickets with $c$ and ladybugs with $c$ .

So, we are tolde there are 10 less grasshoppers than crickets:

$g=c-10$ (1) We have the first equation

Then, we are told there are 5 less crickets than ladybugs:

$c=l-5$ (2) This is the second equation

If $g=5$ and we substitute this in both equations we will have:

$5=c-10$ (3)

Isolating $c$ :

$c=15$ (4) There are 15 crickets

Substituting (4) in (2):

$15=l-5$ (5)

Isolating $l$ :

$l=20$ There are 20 ladybugs

Therefore:

There are 15 crickets and 20 ladybugs
