Two consecutive odd number have the form: 2n+1; 2n+3.
We have:
(2n+1)(2n+3)=399
=> 4x^2+8x+3=399
=> 4x^2+8x-396=0
=> 4(x+11)(x-9)=0
=> x=-11; x=9

Which input value produces the same output value for the two functions on the graph? x = −1 x = 0 x = 3 x = 4
grin007 [14]
We know that
The intersection point of both graphs is a common point for both functions, for which for the same input value, both functions will have the same output value.
so
the point of intersection is
for an input value equal to
the output value for both functions is
therefore
the answer is the option
X= 4

What is the value of x? Round to the nearest tenth <br> Need help fast!!
lesantik [10]
The answer is actually 7.0 because the lengths of the triangle are both going to be 5 and the hypotenuse is then 5 square root of 2 which is 7.07 so if you round it’s 7.0

In the figure, . Find x and y.
zloy xaker [14]

Answer:

The answer to your question is x = 52° and y = 137°

Step-by-step explanation:

Process

1.- Find the value of x using the large right triangle, remember that the sum of the internal angles in a triangle equals 180°.

   x  + 38 + 90 = 180

  x = 180 - 90 - 38

  x = 52°

2.- To find y, we notice that x and y -9 are supplementary angles so their sum gives 180°.

           x + y - 9 = 180

Substitution

          52 + y - 9 = 180

          y = 180 + 9 - 52

          y = 137°

What is the circumference of the circle? r=6.4
nignag [31]

Answer:

C = 40.2124

Step-by-step explanation:

The formula for circumference is

C = 2*pi*r

where r is the radius.

Substitute what we know.

C = 2 * pi * 6.4

C = 12.8 * pi

If we use substitute pi in, we get

C = 40.2124
