How to do it i don’t understand it

When we are given a function f(x) and we are asked for f(a) [a is any number], it means to replace (or substitute) a into x in the function (x=a)

In this problem, we are asked to replace x with 2 in f(x), the first equation, and replace x with 3 in the second equation.

It looks like this:

f(2) = 2^3 + 5(2)^2 = 8 + 5(4) = 8 + 20 = 28

g(3) = 2(3) + 4 = 6 + 4 = 10

We finally just add these two numbers from f(2) and g(3) and get 28 + 10 = 38

Mary has 60 candy pieces and 45 chocolates. She wants to distribute the candy to her little sister's friends at her birthday par
Anna11 [10]

Answer:

5 friends

Step-by-step explanation:

Candy pieces = 60

Chocolate = 45

What should be the smallest number of her sister's friends for the distribution of candy and chocolate so each friend gets an equal number of candy pieces and chocolates in a way that there should not be left any chocolate or candy pieces left over?

To calculate this, find the lowest factor of 60 and 45

60:

Factors = 2, 4, 5, 6,

45:

Factors= 3, 5, 9

The lowest common factor of 60 and 45 is 5

The smallest number of her sister's friend so each person get an equal number of candy pieces and chocolate so there won't be any leftover is 5

That is

If there are 5 friends at the birthday party

60 candy pieces among 5 friends

= 60/5

= 12 pieces each

45 chocolate among 5 friends

= 45/5

= 9 each
