Find area of one triangle
---------------------------------------------
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 9 x 11.75
Area of triangle = 52.875 ft²
---------------------------------------------
Find area of two triangles
---------------------------------------------
Area of 2 triangles = 52.875 x 2
Area of 2 triangles = 105.75 ft²

Find the cost of the flower beds
---------------------------------------------
1 ft² = $4.25
105.75 ft² = 105.75 x 4.25

Answer:
18 Minutes
Step-by-step explanation:
Simon and sophie each do a fraction of the job per minute like this:
-Simon does 
per minute (if we multiply this by 30 we have the completed job)
-Sophie does 
of the job per minute (again if we multiply this by 45 we have the completed job)
We will add this two to know how much of the job they do together in a minute:
They will do 
of the job per minute.
So the total time will be when they do 
, we can put this in one equation like this:
where x is the total times we need to do of the job to complete it. We solve for x:
Answer : p(x)= x^2 -x+1

Answer:
4 and 9
Step-by-step explanation:
I am going to use an upper case E for the symbol in the answers. The E symbol means "is a member of set..."
So " 1 E A " means "1 is a member of set A."
And " 4 E A" means "4 is a member of set A.
Now at the beginning of the question they told you what numbers were in which sets. 1 through 9 are in set U. But only 4 and 9 are in set A. The contents of the set are listed in between a pair of grouping symbols { } that are kind of squiggly brackets. That's how you know what is in the set.
Since set A only contains 4 and 9, those are your two correct answers:
"4 E A" AND "9 E A"
