Write a algebraic expression for “the product of twice a number and the difference of that number and 7” a 2x(7-x)
b 2x(x-7)
c 2x-(x-7)
d 2(x-7)

b

Step-by-step explanation:

for instance when you multiply that 2x it will multiply the one inside (x-7)

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
