The value of U and V will be (x – 3) and 8y, respectively. Then the correct option is A.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression is given below.
⇒ (U + V)(U – V)
Where U and V are either constant or single variable expression.
Then the expression will be
⇒ U² – V²
Then the value of U and V will be (x – 3) and 8y, respectively.
Then the correct option is A.

Answer:
2(x-5)(x+4)
Step-by-step explanation:
2x^2 − 2x − 40
Factor out a 2
2(x^2 -x -20)
What 2 numbers multiply to -20 and add to -1
-5*4 = -20
-5+4 = -1
2(x-5)(x+4)
Answer:
19.8
Step-by-step explanation:
Because 10% of 18 is 1.8 so 1.8 + 18 =19.8
Answer:
A. True
Step-by-step explanation:
Stepwise regression is a variable-selection method for independent variables.
Stepwise regression helps us to recognize and choose the most handy descriptive variables from a list of several reasonable independent variables.
It entails a series of steps that is drafted to locate the most handy X-variable to incorporate in a regression model. During each step of the course of action or method, each X - variable is estimated by applying a set criterion to determine if it is meant to exist in the model.
The basis for selection can be choosing a variable which satisfies the stipulated criterion or removing a variable that least satisfies the criterion. A typical illustration of such criterion is the t value.
