Answer:
the teacher had 503 dominoes for the game.
Step-by-step explanation:
In order to find the answer, first you have to find the amount of dominoes the teacher purchased by multiplying the number of packs for the number of dominoes in each pack:
7*55=385
Now, since the stament indicates that the teacher already had 118 dominoes to use in the game, you have to add this amount to the number of dominoes that were purchased:
385+118=503
According to this, the answer is that the teacher had 503 dominoes for the game.
Answer:
Perimeter=2L+2w
P=2(x+1)+2(x-3)
P=2x+2+2x-6
P=4x-4
Area=Lxw
A=(x+1)x(x-3)
A=x^2-3x+x-3
A=x^2-2x-3

Answer: 
My step-by-step explanation:
- <u><em>We would use the formula πr2 (pi x radius x radius)
</em></u>
<em> </em><u><em>2.In this problem we were given the diameter of 6, in order to find the radius, you just divide by 2</em></u>
- <u><em>
And so we find: 6mm÷2=3mm
</em></u>
3. So now that we have our radius, we can just plug the numbers into the formula. So this would be:
- <u><em>πr2= 3.14 x 3 x 3= 28.26mm2</em></u>
<u><em /></u>
<u><em /></u>
Hope this helps you!
