So you gotta use the AC method. What two numbers multiply to 4 and add to negative 5? It’s -4 and -1. Now you split up the -5 and then factor
I will show you how. 4x^2 -4x -1x +1
Now factor that —> 4x(x-1) -1 (x-1) see how there are two (x-1)?
We simplify it to (x-1)(4x-1) I took the two numbers of the outside and put them together. Now see that you multiply it out you get ur original unfactkred equation
The first picture.
The length of the base is horizontal and extends to 2b.
Therefore the coordinate of N is (2b,0)
You can write it as word form and expanded form.
Word: Two hundred ninety-three thousand, eight hundred five.
Expanded: 200,000 + 90,000 + 3,000 + 800 + 5
16.6% is the same as 0.166, therefore 377ml total x 0.166 = 62.6ml are acid
Answer:
it has 5 hopefully this helps you with work
