14. The sum of two consecutive numbers is 73. What are the numbers?

NeTakaya

Consecutive numbers can be written as such:
n + (n + 1) = 73

Open the parentheses and simplify:
2n + 1 = 73

Subtract 1 from both sides:
2n = 72

Divide both sides by 2:
n = 36

The numbers are 36 and 37

What is the missing constant term in the perfect square that starts with x2 – 16x?

andre [41]

Answer:

Step-by-step explanation:

the expression is

x² - 16x + _

the constant term is the square of the number residing with x divided by 2

the number number x = 16

therefore the constant term is (16/ 2)²

= 8²

= 64

the formula being used here is

(x + a)² = x² + 2ax + a²
