Answer:
28x^2+16x-12
Step-by-step explanation:
(4x+4)(7x-3)
28x^2+28x-12x-12
28x^2+16x-12
The 10 values of reported height are ...
... 61, 68, 57.5, 48.5, 75, 65, 80, 68, 69, 63
Their total is 655, so their average is 655/10 = 65.5 . . . . . your 3rd selection
The answer would be -1/12 .
2/3 - -3/4=-1/12
2/3=8/12
-3/4=-9/12
8/12- -9/12=-1/12
