What is the middle term of the product of (x - 4)(x - 3)? -x x -7x

The middle term of the equation is  (x - 4)(x - 3) is -7x .

Step-by-step explanation:

As given the expression in the question be as follow .

= (x - 4)(x - 3)

First open the bracket and simplify the above terms .

=  x × x - x × 3 - 4 × x -4 × -3

= x² -3x -4x + 12

= x² -7x + 12

Therefore the middle term of the equation is  (x - 4)(x - 3) is -7x .

step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
