Q. Todd 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 Todd 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: Calculate the total number of major scales Todd memorized in 44 lessons. Each lesson, he memorized 22 major scales. So, 44 lessons ∗* 22 scales per lesson =8= 8 major scales.
  2. Calculate Minor Scales: Calculate the total number of minor scales Todd memorized in 44 lessons. Since he memorized xx minor scales per lesson, for 44 lessons it's 4×x=4x4 \times x = 4x minor scales.
  3. Add Total Scales: Add the total major scales and minor scales together to find the total number of scales memorized. 88 major scales + 4x4x minor scales = 8+4x8 + 4x scales in total.
