Answer: c= $( 5 x 5.20)
Step-by-step explanation:
Given: Total people =5
Money paid by each person = $5.20
Total cost of the sundae = (Number of people ) x (Money paid by each person)
Total cost of sunday : c= 5 x ($5.20)
i.e.Total cost of sunday = $(5 x 5.20)
i.e.Total cost of sunday = $ 26
Hence, the required equation to represent the total cost (c) of the sundae:
c= $( 5 x 5.20)
Answer:
15-5y
Step-by-step explanation:
To distribute, multiply everything inside the parentheses by the number outside the parentheses.
5(3-y)
Multiply 5 by 3-y
(5*3)+(5*-y)
15-5y
a. 
b. x = ∛-1 and -3
<h3>How to expand the expression</h3>
a. Given
(x² + 2)²
First, we open up the bracket
Multiply through
Collect like terms
b. Let's factorize
Find the factors of 3 that are products of 4, they are 3 and 1
Use it to replace 4x as 3x and x
Let's make the expression two
Find the common factor
So,
and 
and x = -3
Thus, x = ∛-1 and -3
