SUMMARY
This discussion focuses on solving two mathematical problems involving algebra and geometry. The first problem requires calculating the new dimensions of a chocolate bar after reducing its volume by 20%, while maintaining its thickness. The original dimensions are 12 cm in length, 7 cm in width, and 3 cm in thickness, leading to a new volume of 201.6 cm³. The second problem involves finding the value of k in the quadratic equation x² - kx + 4 = 0, specifically when it has a repeated real solution, which is determined by ensuring the discriminant (b² - 4ac) equals zero.
PREREQUISITES- Understanding of volume calculation (lwh) for rectangular prisms.
