Todd took 4 piano lessons last month. For each lesson, he memorized 2 major scales and x minor scales. Pick all the expressions that represent how many scales Todd memorized last month. Multi-select Choices: (A)2 + 4x (B)4(2 + x) (C)8 + 4x (D)4 + 2x

Calculate Major Scales: Calculate the total number of major scales Todd memorized in 4 lessons. Each lesson, he memorized 2 major scales. So, 4 lessons * 2 scales per lesson = 8 major scales. Calculate Minor Scales: Calculate the total number of minor scales Todd memorized in 4 lessons. Since he memorized x minor scales per lesson, for 4 lessons it's 4 * x = 4x minor scales. Add Total Scales: Add the total major scales and minor scales together to find the total number of scales memorized. 8 major scales + 4x minor scales = 8 + 4x scales in total.

Calculate Major Scales: Calculate the total number of major scales Todd memorized in $4$ lessons. Each lesson, he memorized $2$ major scales. So, $4$ lessons $*$ $2$ scales per lesson $= 8$ major scales.
Calculate Minor Scales: Calculate the total number of minor scales Todd memorized in $4$ lessons. Since he memorized $x$ minor scales per lesson, for $4$ lessons it's $4 \times x = 4x$ minor scales.
Add Total Scales: Add the total major scales and minor scales together to find the total number of scales memorized. $8$ major scales + $4x$ minor scales = $8 + 4x$ scales in total.
