B. Each side of a square is equal. So every side is 5. Formula for area is length x width. So multiply 5 and 5. Answer is 25.
Deal 1 is the better deal because if it was $100, then 1 would be $60 and 2 would be $65.
The numeric value of the expression -a² - 2bc - |c| for a = -3, b = -5 and c = 2 is of 9.
<h3>How to find the numeric value of an expression?</h3>
The numeric value of an expression is found replacing each letter by it's attributed value.
In this problem, the expression is:
-a² - 2bc - |c|
The attributed values are:
a = -3, b = -5 and c = 2
Hence the numeric value will be given by:
-a² - 2bc - |c| = -(-3)² - 2(-5)(2) - |2| = -(9) + 20 - 2 = -9 + 18 = 9.

Answer:
There are 84 men and 16 women in the U.S Senate.
Step-by-step explanation:
We are given the following in the question:
Let x be the number of males and y be the number of females.
Total members = 100
Thus, we can write the equation:
Men in the U.S Senate totaled 4 more than five times the number of woman.
Thus, we can write the equation:
Solving the two equations by substitution method, we have,
Thus, there are 84 men and 16 women in the U.S Senate.
