Answer:

  A = -9, B = 65

Step-by-step explanation:

Take the square root of both sides of the equation:

  h + 9 = ±√65

Subtract 9 from both sides of the equation:

  h = -9 ± √65

Comparing this to the form

  h = A ± √B

we see that A = -9 and B = 65.

_____

A lot of math is about matching patterns of numbers and variables. Here, you're asked to match the expression -9±√65 to the pattern A±√B and identify the values for A and B that make these expressions identical.

It should not be difficult to see that the stuff on the left side of ± is the value of A. That stuff is -9.

The stuff under the radical is the value of B. That stuff is 65.

How can a rational number and irrational number when multiplied together make a irrational number ?
pochemuha

Answer:

"The product of a rational number and an irrational number is SOMETIMES irrational." If you multiply any irrational number by the rational number zero, the result will be zero, which is rational. Any other situation, however, of a rational times an irrational will be irrational

A better statement would be:

"The product of a non-zero rational number and an irrational number is irrational

What are the solutions to the equation <br><img src="https://tex.z-dn.net/?f=2%20%7Cx%20-%202%7C%20%20-%208%20%3D%2020" id="TexF

The solutions of the equation are -12 and 16

Step-by-step explanation:

Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative, if IxI = a, where a > 0, then

  • x = a
  • x = -a

∵ 2Ix - 2I - 8 = 20

- At first add 8 to both sides

∴ 2Ix - 2I = 28

- Then divide both sides by 2

∴ Ix - 2I = 14

Now By using the notes above equate x - 2 by 14 and -14

∵ x - 2 = 14

- Add 2 to both sides

∴ x = 16

∵ x - 2 = -14

- Add 2 to both sides

∴ x = -12

The solutions of the equation are -12 and 16
