Answer: x = 46
Step-by-step explanation: 20 + (5 + 7) = x - 14, 20 + (12) = x - 14
! is factorial
it means multipliy all numbers from 1 to that number together
example
1!=1
2!=2*1
3!=3*2*1
etc
some things to note
7!*8=8!
4!*5*6=6!
so we can rewrite it as
=
=
Answer:
22.43
Step-by-step explanation:
three points ==> it's a triangle
so we will just have to calculate the length of each side
U & V has the same y-coordinate, which means UV is a horizontal line ==>
UV = 3 - (-2) = 5
V & W has the same x-coordinate, which means VW is a vertical line ==>
VW = 4 - (-4) = 8
UW is not a horizontal line nor a vertical line, so we will have to calculate it using distance formula
UW = sqrt { [3 - (-2)]^2 + [-4 - 4]^2 } = sqrt{25 + 64} = sqrt(89) ~~ 9.43
so the perimeter of the polygon is UV + VW + UW = 5 + 8 + 9.43 = 22.43
The answer is 36. Since 2 pies are 8 dollars that means 1 pie is 4 dollars. Take 144 and divide that by 4 and you get 36! Hope that helped
