If a number is increased by its square, the result is 72 find the number

Mathematics
1 answer:
gregori [183]2 years ago
8 0
Translating into a mathematical equation:

n + n^2 = 72

Rewriting,    n^2 + n - 72 = 0
Factoring,    (n+9)(n-8) = 0
Solving for n:  n = -9 or n = 8

You must check both answers before accepting one, the other or both.

Example:  suppose we check out n = 8.  Then  8 + 8^2 = 72 is true, and n = 8 is a solution.  Is n = -9 a solution?  Try it.

The fish is 25 millimeters long. the guinea pig is 25 centimeters long whats the difference
PilotLPTM [1.2K]
Every millimeter is 1/10 of a centimeter, so 1 mm = 0.1 cm and 50 mm = 5 cm. This means that 25 mm can be re-written as 2.5 cm, and we can then find the difference by doing 25 - 2.5 = 22.5 cm. If you were looking for a different type of answer, you can also say that 25 mm is 10 times less than 25 cm.

I hope this helps!

Which equation results from applying the secant and tangent segment theorem to this figure? x(x 2) = (x 4) x(x 4) = (x 2) x(x 4)
fomenos

The equation which is results from applying the secant and tangent segment theorem to the provided figure is,

x(2x +4) = (x +2)^2

<h3>What is secant and tangent segment theorem?</h3>

The secant-tangent theorem tells the relation of the line segment made by a tangent and the secant lines with the connected circle.

According to this theorem, if the tangent and secant segments are drawn from an exterior point, then the square of this tangent segment is equal to the product of the secant segment and the line segment from that exterior point.

The image of the given problem is attached below. In the attached image, the tangent is given as,

T=x+2

The secant is shown in the image has the value,

S=x+x+4\\S=2x+4

Now according to the secant tangent theorem,

x(2x +4) = (x +2)^2

Hence, the equation which is results from applying the secant and tangent segment theorem to the provided figure is,

x(2x +4) = (x +2)^2
