The value of expression b is eight times the value of expression a without evaluating expression a, determine what number belongs in the box in expression b. explain how you determined this question. expression a: 4×[(1.5+100.25)x3.65] expression b : ? ×[(1.5=100.25)x3.65]

The first thing we are going to do for this case is to write the following expression:
 Expression B = 8 * (Expression A)
 Substituting we have:
 Expression B = 8 * (4 × [(1.5 + 100.25) x3.65])
 Then, rewriting:
 Expression B = 32x [(1.5 + 100.25) x3.65]
 
 the number that belongs in the box in Expression B is:
 32

Whose mistake? can you give more details to what the question is asking?
