What is the product of (x − 3) and (x + 7)?

The product of (x-3) and (x+7) is x² + 4x - 21

Step-by-step explanation:

The product of (x-3) and (x+7) is x² + 4x - 21

The product of (x - 3) and (x + 7) can be found as follows:

(x - 3)(x + 7)

open the bracket by multiplying

Therefore,

x(x) +x(7) - 3(x) - 3(7)

x² + 7x - 3x - 21

combine like terms

x² + 4x - 21

x - 21

Step-by-step explanation: If you put a one in front of each part of the equation, you would get 1(x - 3) * 1(x + 7). From there you would get 1x - 3 * 1x + 7. Then you multiply -3 * 7, which would equal -21. Therefore, the answer is "x minus 21".

Step-by-step explanation:

Design one would work better because the students get to see both materials (each on one foot) and if they do the same things each day with both feet, they can test how the material works with the activity...If that makes sense
