3x° = (5x-20)° [Interior Alternate Angle]
=> 3x° = 5x° - 20°
=> 5x° - 3x° = 20°
=> 2x° = 20°
=> x° = 
<h3>=> x° = 10°</h3>

Given expressions;
f(x) = x² + 6x + 7
g(x) = 8x² - 2
h(x) = 3x + 4
k(x) = x - 3
Find f(2) - g(2). k(2)
f(2) = 2² + 6(2) + 7 = 23
g(2) = 8(2)² - 2 = 30
k(2) = 2 - 3 = -1
Now, f(2) - g(2). k(2) = 23 - (30)(-1)
= 53
The solution to the problem is 53
Our basis would be 204 pounds. His original weight, 6 week ago, must be
204 + 2(6) = 216 pounds
But, we have to find the number of weeks having known the present weight (204 pounds) and the target weight (189). The linear equation would be

189 = 204 - 2(number of weeks)
Number of weeks = (204-189)/2
Number of weeks = 7.5
The total number of weeks would then be 6 weeks + 7.5 weeks. It would take Omar 1
3 and a half weeks since he started his diet to reach his target weight.
The answer to that would be D. 54,299
