The problem says that line TQ is 18 units. The little red line through TQ and TR means that both lines are the same, so TR also equal 18 units.

We can solve for x in the equation for TR :

2x+10 = 18
Subtract 10 from each side:

2x = 8

Divide both sides by 2:
x = 4

Because TQ and TR are identical, RS and QS are also identical so we can replace X with 4 in the equation for QS:

9(4) -11 = 36 - 11 = 25

RS = 25 units.

3/4 because 1/2 equals 50% and 1/4 plus that would be 75% less than 6/8

A^3+a+a^2+1 2a^2+2ab+ab^2+b^3

Vikentia [17]

$\frac{a^3+a+a^2+1}{a^3+a^2+ab^2+b^2} \cdot \frac{2a^2+2ab+ab^2+b^3}{a^3+a+a^2b+b} =\frac{a(a^2+1)+1(a^2+1)}{a^2(a+1)+b^2(a+1)} \cdot \frac{2a(a+b)+b^2(a+b)}{a(a^2+1)+b(a^2+1)} =\\\\=\frac{(a^2+1)(a+1)}{(a+1)(a^2+b^2)} \cdot \frac{(a+b)(2a+b^2)}{(a^2+1)(a+b)} = \frac{2a+b^2}{a^2+b^2}$
