1 A Gauteng football club is making a model of a playing field so they can build other development clubs. They buy \( 2 \mathrm{~m}^{2} \) of artificial grass. a Is the number of squares of grass covering the entire model field the area of the field or the perimeter of the field? b How much artificial grass will they need if the model field is 160 cm long and 100 cm wide? c They can buy pieces of model wire fencing in rolls \( 0,5 \mathrm{~m} \) long. How many rolls of wire do they need to fence the model field? d Is the amount of wire the same as the area of the model field or the

'altezza di un triangolo equilatero misura \( 34,6 \mathrm{dm} \). Calcola il perimetro e l'area del riangolo. \( \quad\left[120 \mathrm{dm} ; 692 \mathrm{dm}^{2}\right] \)

2 . What is \( 25 \% \) of \( 15 ? \) A) 3 B) 3.75 C) 37.5 D) 375

Solve for all values of \( x \) \[ \log _{2}\left(x^{2}+3 x\right)=2 \]

A little league baseball team is ordering hats. Graph of a line, origin 0 . Horizontal axis, hats ordered, scale is 0 to 11 , by 1 's. Vertical axis, total cost, scale is 0 to 220 , by 20 's. Line starts at approximately 0 comma 35 , and passes through 6 comma 120, and 9 comma 160. The graph shows the relationship between the total cost, in dollars, and the number of hats ordered. What does the slope of the graph tell us in this situation?

Solve for all values of \( x \) \[ \log _{6}\left(2 x^{2}+6 x\right)=2 \]
