Answer:
7920
Step-by-step explanation:
12C3 × 9C2
= 220×36
= 7920
Perimeter = 2 x Length + 2 x Width
Perimeter = 2(20) + 2(12) = 64 feet.

Answer: Perimeter = 64 feet.

You plug the x value into whichever function it applies to. X represents the number of shirts ordered. So for example, the first question asks the total cost if you order 57 shirts. Look at the piecewise function. If says is x>50 (or equal), you use the equation 14x + 20. 57 is greater than 50 so plug it into the equation. (14)(57) + 20 = 818. You should be able to do the rest now. If you have any more questions, you can ask.
Zero is the only thing that makes sense
Answer:
-9
Step-by-step explanation:
We are given the expression m–[(m–n)÷(−2)](−5). Substituting -4 for m and -6 for n, we get:
-4–[(-4 + 6)÷(−2)](−5)
We must do the work that appears inside parentheses first:
-4–[( 2 )÷(−2)](−5)
Next we must do the work that appears inside square brackets:
-4–[ -1 ](−5)
Multiplication comes next. The above expression becomes:
-4 - [ 5 ]
which in turn comes out to -9
