Let m = X^2 + 3.
Tpy6a [65]

The Equation in terms of m, m^2+7m+10=0

What is substituting in the equation ?

substituting means changing or replacing the values in the given equation.

Calculation:

Given equation is (x^2+3)^2+7x^2+21=-10

            and m= X^2 + 3.

make the given equation in the form X^2 + 3,

             now,

                     (x^2+3)^2+7x^2+21=-10

                     (x^2+3)^2+7(x^2+3)=-10

             where,

                      X^2 + 3= m

              after putting the value or replacing the values

             we get, m^2+7m=-10

                      m^2+7m+10=0

          the above equation is in the form of "m".

The Equation in terms of m, m^2+7m+10=0

How many millimeters are there in 16 meters
Anika [276]
One of the very nice features of the metric system of measurements is that there is a set of standardized prefixes that can be applied to any of the units. Some of the more common ones are
.. micro- . . . one millionth
.. milli- . . . . one thousandth
.. centi- . . . .one hundredth
.. kilo- . . . . .one thousand

Thus, one millimeter is 1/1000 = 0.001 meter. There are 1000 of them in 1 meter, so
.. 16 m = 16000 mm

german

Answer:

The result after adding a set of numbers or is called a sum.

Step-by-step explanation:

Consider the provided information.

The four mathematical operations are:

+,-,\times ,\div

The sign + is used to add numbers.

The sign - is used to subtract the numbers.

The sign × is used for the product of the numbers.

The sign ÷ is used for division of the numbers.

When we add two or more number by using the operator + the obtained number or value is called the sum of the numbers.

For example:

Consider the number: 2 + 5 if we add the number the resulting value will be 7.

The number 7 is the sum of 2 and 5.

Thus, the result after adding a set of numbers is called a sum.
