Hiro painted his room. After 3 hours of painting at a rate of 8 square meters per hour, he had 28 square meters left to paint. Let \( y \) represent the area (in square meters) left to paint after \( x \) hours. Complete the equation for the relationship between the area and number of hours.

Classify triangles TNN A triangle has angle measurements of \( 58^{\circ}, 101^{\circ} \), and \( 21^{\circ} \). What kind of triangle is it?

Determine whether the statement is true or false. If \( \mathrm{P}(\mathrm{x})=(\mathrm{x}-3)^{2}(\mathrm{x}+6)^{5} \), then the graph of the polynomial function \( \mathrm{y}=\mathrm{P}(\mathrm{x}) \) crosses the x -axis at \( (3,0) \). Choose the correct answer below. A. The statement is true because \( (\mathrm{x}-3)^{2} \) is a factor of the given polynomial function \( \mathrm{P}(\mathrm{x}) \), and the exponent, 2 is odd. Thus, the graph crosses the x -axis at \( (3,0) \). B. The statement is false because \( (\mathrm{x}-3)^{2} \) is a factor of the given polynomial function \( \mathrm{P}(\mathrm{x}) \), and the exponent, 2 is odd. Thus, the graph is tangent to the x -axis at C. The statement is true because \( (\mathrm{x}-3)^{2} \) is a factor of the given polynomial function \( \mathrm{P}(\mathrm{x}) \), and the exponent, 2 is even. Thus, the graph crosses the x -axis at D. The statement is false because \( (\mathrm{x}-3)^{2} \) is a factor of the given polynomial function \( \mathrm{P}(\mathrm{x}) \), and the exponent, 2 is even. Thus, the graph is tangent to the x -axis at \( (3,0) \).

Divide \( \frac{2}{3} \) and \( \frac{1}{2} \cdot w \)

Consider the list of data, which represents the total number of online orders placed during a company's first 8 months of operation. \( 18,23,39,45,56,56,61,78 \) If a 129 is added to the data set, which statement will be true? Both the mean and median will decrease. Both the mean and median will increase. The mean will decrease, and the median will increase. The mean will increase, and the median will decrease.

(c) Melisha spent \( 75 \% \) of her birthday money and gave \( 50 \% \) of what was left to charity. She then put the remaining R60 in her savings account. How much money did she receive for her birthday?
