In the diagram below of triangle ABC, D is a midpoint of AB and E is a midpoint of BC. If DE = 9x – 20, and AC = 5x + 12, what is the measure of AC?
B
D
E
А

yes because they have the same amount of green and blur marbles.

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
