The correct Option is (A) 35x^3 - 16x^2 + 44x - 48

Explanation: The product of the polynomials (5x^2 + 2x +8)(7x-6) is:

(5x^2)(7x-6) + 2x(7x-6) +8(7x-6)

35x^3  -30x^2 + 14x^2 - 12x + 56x - 48

Equation : (7x-4)+(3x-3)+(x) = 180
In the equation the sum of the internal angle in the triangle is 180 degrees. Use this equation to figure the sum of angle in any quadrilateral 180*(number of sides-2)
Solve the equation
Put all similar variable on one side
7x+3x+x-4-3=180
11x-7=180
11x=180+7
11x=187
x = 187/11
x = 17
Now find the angles by plugging in x
Angle F (7*17-4) = 115 degrees
Angle G (x) = 17 degrees
Angle E (3*17-3) = 48 degrees
If you add 115+48+17 you will get a sum of 180 this shows your answer is right


Angle F = 115
Angle G = 17
Angle E = 48
