(x12) ^5x (x-2)^9 ×___=(x40)^5

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

the answer is

step-by-step explanation:

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
