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.
Answer:
X = 16
Step-by-step explanation:
Notice that we are in the presence of two similar triangles, one larger than the other. The larger triangle is AED, and the smaller one is ACB.
Since there are similar triangles, we can write a proportionality between their known sides:

notice that AD = x + 6
AB = x
ED = 11
CB = 8
So now we can re-write the proportion and solve it for the unknown "x":

To solve this you must isolate x. First add 1 to both sides
x² - 1 + 1 = 0 + 1
x² = 1
Now you must take the square root of both sides to cancel out the square from the x
√x² = √1
x = 1 and x = -1
When you take the square root of a number you must remember to take both the positive and negative of the number
