What is the unknown term.<br>in the seqpence 4.5, 5.4,____7.2<br><br>A.6.2 or B. 63​
harina [27]

Answer:

6.3

Explanation:

To get from 4.5 to 5.4, you need to add 0.9. If you add 0.9 two more times, you get 7.2. Therefore, the middle term should be 6.3. I don't know if you made a typo and forgot the decimal when writing the options cause it says "63", but I believe the answer is 6.3.

Which expression is equivalent to x^4 + 4x^2 - 45?
Nikitich [7]

Answer:

( {x}^{2}  - 5)( {x}^{2}  + 9) = 0

Step-by-step explanation:

The given expresion is

{x}^{4}  + 4 {x}^{2}  - 45 = 0

We can rewrite this as:

({ {x}^{2}) }^{2}  + 4 {x}^{2}  - 45 = 0

We obtained a quadratic equation in x²

Let us split the middle term to get:

({ {x}^{2}) }^{2}  + 9 {x}^{2}  -  5{x}^{2}  - 45 = 0

We factor by grouping to get:

{x}^{2} ( {x}^{2}  + 9) - 5( {x}^{2}  + 9) = 0

We factor further to get:

( {x}^{2}  - 5)( {x}^{2}  + 9) = 0

The correct answer is A.
