(x+3)(x-4) what is the middle term in he simplified product?

The middle term is - x

Step-by-step explanation:

Use Foil

F: x * x = x^2

O: -4 * x = - 4x

I: 3*x = 3x

L: 3 * - 4 = -12

F+O+I+L = x^2 - 4x + 3x - 12

F+O+I+L = x^2 - x - 12

the correct answer is 5

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
