Apply slip and slide
a^2-3a-4
(a-4)(a+1)
(a-2)(2a+1)
Find zeros
a-2=0
a=2
2a+1=0
2a=-1
a=-1/2
Final answer: {-1/2, 2}
Answer:
Part A: x=3
Part B: 6oz
3x=18
Step-by-step explanation:
Part A-
So, he needs 3 oz for each sandwich.
This gives us 3 for the equation.
The question says that we need an equation for this.
If we need an equation, we could write something like
x=3
There's really not anything else that we could write here.
Part B-
We now have something that we need to write.
He has 18 oz for sandwiches.
Each sandwich needs 3 oz.
So, we can write something like 3x=18
Then we could solve the equation by dividing both sides by 3.
This will leave us with x=6
Hope this works!
