Answer:
36
Step-by-step explanation:
Given
x² + 12x
To make the polynomial a perfect square
add ( half the coefficient of the x- term)²
= x² + 12x + 6²
= x² + 12x + 36
= (x + 6)² ← a perfect square
Answer:
interest paid = $206.25
course = $1,875.00
total = $2,081.25

Answer:
(x−3)(x+8)
Step-by-step explanation:
Let's factor x2+5x−24
x2+5x−24
The middle number is 5 and the last number is -24.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 5
Multiply together to get -24
Can you think of the two numbers?
Try -3 and 8:
-3+8 = 5
-3*8 = -24
Fill in the blanks in
(x+_)(x+_)
with -3 and 8 to get...
(x-3)(x+8)
Answer:
(x−3)(x+8)

Answer:
<h3>40 degrees</h3>
Step-by-step explanation:
If the temperature dropped 5 degrees every hour, this can be expressed as;
5 degree = 1 hour
To get the total number of degree dropped fro 8hours, we will say;
x degree = 8hours where x is the temperature drop in all
Solving both equality
5 degree = 1 hour
x degree = 8 hours
cross multiply
x * 1 = 5 * 8
x = 40 degrees
<em>Hence the total temperature drop in all is 40°</em>
