My natural tendency is to FIOL instead of FOIL but it doesn't matter.


(x+5)(x-6)


Firsts: x times x


Outers: x times -6 = -6x


Inners: 5 x


Lasts: 5(-6)=-30


Outers+Inners = -6x + 5x = -x


Answer: -x



(x-2)(x-3)=x^2-3x-2x+6=x^2-5x+6


Answer: second choice

Question in image. :)
quester [9]

a. f(a) =5a+12

we have 1. a=6

Therefore, where ever we find a we'll substitute in 6

f(6) =5(6) +12

6f=30+12

6f=42

so therefore 1. a=6 will match c on the right

2. a=2

f(2) =5(2) +12

2f = 10+12

2f = 22

therefore 2. a=2 will match a on the right

3. a=4

f(4) =5(4) +12

4f=20+12

4f=32

therefore 3. a=4 will match d on the right

4. a=5

f(5) =5(5) +12

5f=25+12

5f=37

therefore 4. a=5 will match b on the right
