The value of a is 
Step-by-step explanation:
<u>1. Determine the other solution of x</u>
If one value is 5 + 
then the other value is 5 -
<u>2. Use reverse technique to find the equation</u>
(5 + ) (5 - ) = 0
25 - 
+ 
- 
= 0
- + 25 = 0
<u>3. The equation is</u> - + 25 = 0
<u>4. Find the value of a</u>
a is the number with the variable 
therefore it is -

<span>The cost that a carpet cleaning company charges is directly proportional to the number of rooms cleaned. The cost is $22 for each room.</span>
75+ 15x ≥ 140
⇒ 15x ≥ 140 -75
⇒ 15x ≥ 65
⇒ x ≥ 65/15
⇒ x ≥ 13/3
⇒ x ≥ 4 1/3
The final answer is x ≥ 4 1/3~
Answer:
1440°
Step-by-step explanation:
n = number of sides
n-2 x 180
10 - 2 = 8
8 x 180 = 1440°
