Wait for area, wouldn't you just times 13 and 5 and get 65 and then times 23?
Step-by-step explanation:
4.6+4.6=8.12
8.1 to one decimal place
the radius is half the length.
Maggie brought 3 sandwiches to the picnic .
In the question ,
it is given that
Maggie bought oranges and sandwiches to a picnic .
given the number of oranges = 9
also given that , number of oranges was three more than twice the number of sandwiches
let the number of sandwiches Maggie brought to a picnic be x .
So , the number of oranges is = 2x + 3
So , 2x + 3 = 9
Subtracting 3 from both the sides ,
we get ,
2x = 9 - 3
2x = 6
On dividing both sides by 2,
we get ,
x = 6/2
x = 3
Therefore , the number of sandwiches = 3 .

Using Pythagoras theorem :
C = sqrt(a^2 + b^2)
C = sqrt(36+64)
C = sqrt(100)
C = 10 feet
The vertex is at -b/(2A). if you use the foil method it will come out to -(x^2+2x+1)+4. then distribute the negative and simplify the equation (add the four) the equation comes out to be -x^2-2x+3. The vertex is at x=2/(2*-1), which is -1. plug -1 into the original equation to find y, (y=-(-1)^2-2*(-1)+3) which is y=4. so the vertex is at (-1,4). then since the parabola opens down (negative a value) and has a maximum at 4, y is always less than or equal to 4. x is all real numbers as it goes on forever. so b is your answer.
