What about if you use the distributive property? You could do 1(x+13) because the 1 would distribute to the x and the 13 making it x+13. Hope that is helpful.

I have no any ideas
Step-by-step explanation:

3-√11
This function is evidently a quartic - a function with 4 roots. The last root has been found using the quadratic formula however, the answer always comes in pairs because the formula is
{b+√(b^2 - 4ac)}/2a and {b-√(b^2 - 4ac)}/2a. Therefore the other root must be 3-√11
Area of trapezoid(A) =(1/2) (b1 + b2)*h
b1= x - shorter base
b2=2x - longer base
A=975 m²
h=50 m
975 =(1/2) (x + 2x)*50
975 = 25*3x
975 = 75x
x=975/75 = 13 m
x= b1 = 13 m
b2=13*2=26 m
b1=13 m,
b2 = 26 m,
