Consider the expression
Factorize the numerator and denominator a difference/sum of cubes:
Expand the denominator:
since <em>x</em> = 2020, and clearly 2020² + 2020 + 1 ≠ 0, so we can cancel the factor of <em>x</em> ² + <em>x</em> + 1. This leaves us with
so that <em>a</em> + <em>b</em> = 673 + 674 = 1347.
The y is going to be 165 if the x is 54 because you need to multiply by 3 each time.
1st one is C and then the 2nd one is B
We would use the sine function because we have an angle the hypotenuse, and the unknown opposite side.
sin(x)=opposite/hypotenuse
sin(60)=x/30
√3/2=x/30 (cross multiply)
30*√3/2=x (divide numerators and denominators by 2)
x=15√3 ft.
So the correct answer is A
Hope this helps
