I think the answer is a=7b*9/2=31.5M
These angles are same side interior angles. They add up to 180 degrees
Base of the rectangle = x
Height of the rectangle = y
Area = length x height
30 = x.y
y = 30/x
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
Step-by-step explanation:
