Each side of a square coffee shop is 9 meters longs. what is the coffee shop's perimeter ?
qaws [65]

Well lets remember that a square has four sides that are all equal.

So if we know one side, we know them all!

And perimeter is all of the sides added up.

Well.. 4 sides that are all 9 meters long? here's the math!

9 + 9 + 9 + 9 = 36

Your coffee shop is 36 meters long

Good Luck! :)

Let f(x)=2x-1 and g(x)=x^2 -3. Find (f o g)(-3)
anzhelika [568]
(f o g)(-3) = (f(g(-3))
Because g is on the inside, we carry out g first.

g(x) = x^2 - 3
Substitute -3 in for x.
g(-3) = (-3)^2 - 3 = 9 - 3 = 6
g(-3) = 6

Next, carry out f on the result of g(-3)
f(6) = 2(6) - 1
      = 12 - 1
      = 11
So the answer is 11.

Express 56 as the product of its prime factors.
BigorU [14]

Answer: 7 x 2 x 2 x 2

Step-by-step explanation:

So 7x8 = 56; 7 is prime, but 8 can be factored further; 8 = 4x2, but the 4 can be factored; 2x2

So now you have the prime factorization of 56= 7 x 2 x 2 x 2

LIMITED TIME PLS HELP: Four, two-person tennis teams played tennis matches. Ivan collected the number of points won by both play
Marina86 [1]

For this, you just need to add up the team points together. Also remember that the problem says "60 pts or less", not "less than 60 pts". This means teams with 60 pts will count for the question.


Team 1: 38+22=60


Team 2: 42+18=60


Team 3: 21+42=63


Team 4: 25+40=65


From the math above, we can conclude that 2 teams had won 60 or less.
