Q. Ruben took 44 piano lessons last month. For each lesson, he memorized 22 major scales and xx minor scales.\newlinePick all the expressions that represent how many scales Ruben memorized last month.\newlineMulti-select Choices:\newline(A) 2+4x2 + 4x\newline(B) 4(2+x)4(2 + x)\newline(C) 8+4x8 + 4x\newline(D) 4+2x4 + 2x
  1. Calculate Major Scales Memorized: Calculate the total number of major scales Ruben memorized in one month. He memorized 22 major scales per lesson and took 44 lessons.\newlineCalculation: 22 scales/lesson ×\times 44 lessons = 88 scales.
  2. Calculate Minor Scales Memorized: Calculate the total number of minor scales Ruben memorized in one month. He memorized xx minor scales per lesson and took 44 lessons.\newlineCalculation: xx scales/lesson ×4\times 4 lessons =4x= 4x scales.
  3. Add Total Scales Memorized: Add the total number of major and minor scales to find the total number of scales memorized.\newlineCalculation: 88 scales + 4x4x scales = 8+4x8 + 4x scales.
