Select the expression that matches the following phrase:

The sum of

and the product of `B`

and `A``x`

.

`expr(["+", ["*", A, "x"], B])`

`expr(["+", ["*", -A, "x"], B])``expr(["+", ["*", A, "x"], -B])``expr(["+", ["*", B, "x"], A])``expr(["+", ["*", -B, "x"], -A])`

What is the product of

and `A``x`

?

What is the sum of

and `B`

?`expr(["*", A, "x"])`

Take the quantity

times `A``x`

, and then add

.`B`

What is the quantity of

times `A``x`

?

What does adding

do?`B`

plus the product of `B`

and `A``x`

.

What is the product of

and `A``x`

?

What is

plus `B`

?`expr(["*", A, "x"])`

The sum of

and the quantity `B`

times `A``x`

.

What is the quantity

times `A``x`

?

What is the sum of

and `B`

?`expr(["*", A, "x"])`

Let's break this problem into smaller and easier pieces.

`A` \times x = \color{orange}{`expr(["*", A, "x"])`}

`A`x`{} + `

`B`

So, the original phrase can be written as

.`expr(["+", ["*", A, "x"], B])`
