Question Elissa earned \( \$ 152.84 \) this week, which was \( \$ 21.65 \) more than she earned last week. How much did she earn last week?

Solve for the roots in simplest form by completing the square: \[ 6 x^{2}-48 x-1374=0 \]

Write down these numbers in ascending order (lowest to highest). \[ 2.1,-4.5, \quad 4.3,-4.2,-2.5,-2 \]

Observe que \( x \) é uma medida variável. A área desse retângulo é dada por: \( \mathrm{A}= \) (base) \( \times \) (altura) Logo: \( A=(x+4) \cdot x \rightarrow \) Aplicando a propriedade distributiva temos: \( A=x \cdot x+4 \cdot x \) \( A=x^{2}+4 x \) A expressão \( A=x^{2}+4 x \) indica que a área \( A \) é funçăo de \( x \), ou seja, depenć de \( x \). E então podemos eserever:

()) Taylor County and Howard County are gathering groups of runners to run a relay race. Taylor County recruits runners in groups of 8 while Howard County recruits runners in groups of 2 . If both counties end up with the same number of runners, what is the smallest number of runners each must have recruited? (1))

In convex polygons, on the other hand, all internal angles are less than and all diagonals lie \( \square \) the polygon.
