Answer:
Ginny made a mistake in step 1 when she identified b = 31. It should be b=-31
Step-by-step explanation:
Ginny factored
as shown:
ac = –180 and
b = 31
36(–5) = –180 and 36 + (–5) = 31
+ 36x – 5x – 30
6x(x + 6) – 5(x + 6)
(x + 6)(6x – 5)
b is the coefficient of x and from the trinomial
, b=-31.
Therefore Ginny made a mistake in step 1 when she identified b = 31. It should be b = –31.
The correct steps are:
:
ac = –180 and
b = -31
36(–5) = –180 and -36+5 = -31


No, because in the first one the 4 is negative, in the second it is positive
No because 21 ft equals 7 yd
which us bigger than 3 yd
