When a number is substituted for the same variable in two expressions, how many times must those two expressions have different values before you know they are not equivalent? Expain.

n+1

Where n is the degree of the expression

Step-by-step explanation:

Equate the expressions and form an equation.

If they are equivalent, this would be an identity

An equation can be satisfied only by the roots if not equivalent.

No. of roots depends on the degree of the equation.

So use atleast one value more than the degree.

For example, if it's a quadratic (degree 2) try 3 values of the variable

If it's a cubic (degree 3), try 4 values.

In general, if degree is n try (n+1) values of the variable

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?

have a splendid day < 3 : )

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
