Answer:
We conclude that exist 286 different ways.
Step-by-step explanation:
We know that a ballroom dance couple has learned 13 different routines and needs to pick 10 of them to prepare for an upcoming local competition.
So, we count that out of 13 different routines we choose 10.
We use the following formula:
We conclude that exist 286 different ways.
Area of a rectangle = Length * width.
Small rectangle A = 1m * 3m = 3 square meters
Big rectangle A = 5m * 6m = 30 square meters.
30 square meters + 3 square meters = 33 square meters
Daniel needs 33 square meters of carpet tiles
The answer is if 5(3x - 7 ) = 20 than 6x - 8 is 2(3x - 4) You get this answer when you factor it.
We have that
F(x)=x²<span>-10x+44
</span><span>Group
terms that contain the same variable
</span>f(x)=(x²-10x)+44
<span>Complete
the square Remember to balance the equation
</span>f(x)=(x²-10x+25-25)+44
Rewrite as perfect squares
f(x)=(x-5)²-25+44
f(x)=(x-5)²+19
this is the equation of a vertical parabola with vertex (5,19)
