The work of a student to find the dimensions of a rectangle of area 8 + 16x and width 4 is shown below:

step 1: 8 + 16x
step 2: 4(4) + 4(12x)
step 3: 4(4 + 12x)
step 4: dimensions of the rectangle are 4 and 4 + 12x

in which step did the student first make an error and what is the correct step?

step 3; 4 + (4 + 12x)
step 3; 4 + (4 ⋅ 12x)
step 2; 4(2) + 4(4x)
step 2; 4(2) + 4x(2)

answer for blank 1:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

10 you would take 50/ .2
