The steepest side of the model, AB, measures 4 inches. What is the length of the other skating surface, AD? 2 StartRoot 2 EndRoot in. 2 StartRoot 3 EndRoot in. 4 StartRoot 2 EndRoot in. 4 StartRoot 3 EndRoot in.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

4

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)
