W=A/L
Take the original A=LW and divide both sides by L to get A/L=LW/L, the Ls on the right cancel out to leave A/L=W

Answer: I’m going to do the first problem with a fully detailed explanation and just answer the other ones! :)
Factoring: v^2-4v-60
The middle number is -4 and the last number is -60.
Factoring means we want something like
(v+_)(v+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -4
Multiply together to get -60
Can you think of the two numbers?
Try 6 and -10:
6+-10 = -4
6*-10 = -60
Fill in the blanks in
(v+_)(v+_)
with 6 and -10 to get...
(v+6)(v-10)
Second Problem: (x-4)(x-9)
Third Problem: 6(x+5)(x+8)
Fourth Problem: (k+5)(k+10)
Fifth Problem: (a-4)(a-4)
The answer to that would be 14.66666666666667
Answer:
