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


Answer:
Option 1 is the correct one given that v=value and t=time.
Step-by-step explanation:
Answer:
$37.50
Step-by-step explanation:
$125 times30%=$37.50
Your answer is -5.
This is because, if you expand the single bracket, you get -6x -3a, and since the other side of the equals sign is -6x + 15, then you need to do 15 ÷ -3 = -5.
I hope this helps!
Answer: Height is 5 units.
Step-by-step explanation:
Alright, lets get started.
The area of the triangle is 
The area is given as 30
The base is given as 12
Plugging the values in formula


Dividing 6 in both sides



Hence the height of the triangle is 5 units.........Answer
