Answer:
x = 7
Step-by-step explanation:
4 + 5(x + 2) = 7x
4 + 5x + 10 = 7x
5x - 7x = - 4 - 10
- 2x = - 14
- x = - 14/2
- x = - 7
x = 7

Given:
A bird was sitting 16 feet from the base of an oak tree and flew 20 feet to reach the top of the tree.
To find:
The length of the tree.
Solution:
A bird was sitting 16 feet from the base of an oak tree.
Vertical distance between bird and base = 16 feet
Then the bird flew 20 feet to reach the top of the tree.
Now, the vertical distance between bird and base = (16+20) feet
So, length of the oak tree is it the sum of 16 feet and 20 feet.
 feet
 feet
 feet
 feet
Therefore, the length of the oak tree is 36 feet.
 
        
             
        
        
        
After 6 years, the difference between owning the house and renting is $12,000.
<h3>What is the difference in owing and renting the house?</h3>
The first step is to determine the total cost of renting the house for six years. 
Total cost of renting the house = rent per month x number of years x number of months in a year 
1500 x 12 x 6 = $108,000 
Difference  = cost of owning - cost of renting 
$120,000 - $108,000  = $12,000
