Length = 2W
P= 2L + 2W
60 = 2(2W) + 2W
60= 4W +2W
60 = 6W
60/6W = 6W/6W
w = 10
Length = 2(10)
Length = 20
P= 2L + 2W
60= 2(20) + 2(10)
60= 40 +20
60 = 60
<h3>
Answer: b = 4 and c = 7.</h3>
===============================================
Explanation:
Comparing y = x^2+bx+c to y = ax^2+bx+c, we see that a = 1.
The vertex given is (-2,3). In general, the vertex is (h,k). So h = -2 and k = 3.
Plug those three values into the vertex form below
y = a(x-h)^2 + k
y = 1(x-(-2))^2 + 3
y = (x+2)^2 + 3
Then expand everything out and simplify
y = x^2+4x+4 + 3
y = x^2+4x+7
We see that b = 4 and c = 7.
I'm not sure what this question means exactly, maybe the principals goal is unrealistic?
Answer:
2
Step-by-step explanation:
let the other leg be x
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 1² = 3²
x² + 1 = 9 ( subtract 1 from both sides )
x² = 8 ( take the square root of both sides )
x = 
=

× = 2 ← exact value
The fraction of the pie Each person will get from Brenda = ( 5 / 24 ) of the pie.
Given,
Brenda has 5/6 of pie with her.
The total number of persons = 4
Now, the fraction of the whole pie each person will take :-
( Number of pie ) / ( total persons )
= ( 5 / 6) / 4
= ( 5 / ( 6 x 4 ) )
= ( 5 / 24 )
Therefore, the fraction of the pie each person get from Brenda = ( 5 / 24 )
