*i know twice as many jokes as my friend does. together we know 60 different jokes. my friend and i both know the same three jokes. how many jokes do i know? how many jokes does my friend know?

Step-by-step explanation:

Together, you know 66 jokes (60 different and 3 that count twice). If you know twice as many as your friend, your friend knows 1/3 of the total number of jokes, and you know 2/3 of them. Your friend knows ...

  1/3 × 66 jokes = 22 jokes

You know 44 jokes, and your friend knows 22 jokes.

Check

Your friend knows 22 -3 = 19 jokes that are different from ones you know, and you know 44 -3 = 41 jokes that are different from the ones your friend knows. 19+41 = 60

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
