Consecutive even integers are 2 apart
they are x and x+2
sum means add
so
they add to 234 so
x+x+2=234
2x+2=234
minus 2 from both sides
2x=232
divide both sides by 2
x=116
x+2=118
the numbers are 116 and 118 and the larger one is 118
Answer:
See below
Step-by-step explanation:
I'll provide an example to help you. Let's say we were solving and we wanted to factor the quadratic on the left side. We can't do that because the factors of -7 don't add up to 5. So we'd have to use the quadratic formula. The quadratic formula is essentially the last resort that will solve all quadratic equations, so it could be seen as a preferred method. But, unless you can factor the quadratic, it's much easier to solve.
Now let's do another one. for example can be written as and we can easily get and as solutions since plugging them into the factors would produce 0 (from the Zero Product Property). If we used the quadratic formula, it would take more time to plug in the variables and solve when we can just simply factor.
Hopefully, this explanation helps you to think of your discussion post!
I think what you are looking for is 5x=300 therefore x=60 so at 60cars he would start to make more.
