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


I also suggest using an app called photomath. It takes you through the steps of solving the equations and gives you the answer as well.
The answer is 78 because when you add all the numbers it equals 780 and you need to divide the end sum by the amount of numbers added to get it. So in the end there were 10 numbers added to equal 780 so 780\10 equals 78
Usually, rugs have a rectangular shape, therefore the section of the living room that Patrick wants to cover is a rectangle.
The area of a rectangle can be found by multiplying the length and the width of the rectangle:
A = l × w
Hence, the most appropriate measurements Patrick should provide are the length and the width of the section of his living room he wants to cover.
the answer is 470
Step-by-step explanation:Because 470+470 which equals 940 and the square root is 30
