$\dfrac{11}{12.1}=\dfrac{x}{66}\qquad\text{cross multiply}\\\\12.1x=(11)(66)\\\\12.1x=726\qquad\text{divide both sides by 12.1}\\\\x=60\\\\Answer:\ B.\ 60$

Write and simplify an algebraic expression to represent the area of the shaded region. The image is below.

Lena [83]

$(x+2)^2 - 1\cdot(x-5) = x^2 + 2\cdot2x + 2^2 - (x - 5) = x^2 + 4x + 4 - x + 5 = x^2 + 3x + 9$

Which of the following is defined by a line parallel to one side of a triangle

Katarina [22]

Answer:

Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.

Step-by-step explanation:

Triangular Proportionality Theorem states that:

If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.

Let us consider the triangle ΔABC as shown in attached figure.

$DE$ ║ $AC$

then

$\frac{BD}{DA} = \frac{BE}{EC}$

Therefore, Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.
