I'm in Technical school second year and I want you to give me some questions to be learning for my exam

Here are some practice questions for your exam:

Question 1: Solve for $x$:

$$5(x - 3) + 2x = 4x + 9$$

Question 2: A circular metal plate has a radius of 7.5 cm. Calculate its area. Use $\pi \approx 3.14$.

$$A = \pi r^2$$

Question 3: A ladder 10 meters long leans against a vertical wall. If the base of the ladder is 6 meters from the wall, what is the height the ladder reaches on the wall?

$$a^2 + b^2 = c^2$$

Here are 3 questions to practice. Send them back when you're ready for solutions or more questions!
