Answer: Formula For Factoring Trinomials (when a =1)
It's always easaier to understand a new concept by looking at a
specific example so you might want to do that first. This formula works
when 'a' is 1. [ In other words, we will use this approach whenever the
coefficient in from of x2 is 1.
1) identify a,b, and c in the trinomial ax2 + bx+c
2) write down all factor pairs of c
3) identify which factor pair from the previous step sums up to b
4) Substitute factor pairs into two binomials

Answer:
The height of the beam is:
Step-by-step explanation:
The radius of the tunnel is r = 15 feet
The distance of the beam from the center of the tunnel is:
We have a right triangle, where:
- The Hypotenuse is 15 feet
- One side is 9 feet
- The other side is the height of the beam
Let's use Pythagoras theorem.
Therefore, the heigh of the beam is:
