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

The ratio of time taken by Henry to time taken by Gavin is 3:5
Step-by-step explanation:
Time taken by Henry for each set = 36 minutes
Time taken by Gavin for each set = 1 hour
We will convert Gavin's time into minutes.
Time taken by Gavin for each set = 60 minutes
Ratio;
Time taken by Henry : Time taken by Gavin
Dividing by 6
Dividing by 2
The ratio of time taken by Henry to time taken by Gavin is 3:5

Answer:Carys earns $10 per hour and earn $1 in hour .
Step-by-step explanation:
Given: Carys calculates the total amount E, in dollars, that she earns for working h hours.
She use the equation to calculate the total amount .
Foe h=1,
hence, she earns $10 in one hour.
Therefore, Carys earns $10 per hour.
Let she earn $1 then put E=1 in the equation, we get
Hence, she earn $1 in hour .
