The value of the given expression (3m - n)² + 4m when m = 63 and n = 45 is equal to 20,916.
<h3>What is an expression?</h3>
An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.
<u>Given the following variables:</u>
Substituting the given variables into the given expression, we have;
Expression = (3m - n)² + 4m.
Expression = (3(63) - 45)² + 4(45).
Expression = (189 - 45)² + 180
Expression = 144² + 180
Expression = 20,736 + 180
Expression = 20,916.

Complete Question:
Evaluate the expression when m = 63 and n = 45. (3m - n)² + 4m.
Answer:
4x³ +2x² + 2x
Step-by-step explanation:
1- Determine the sign
2- Combine like terms
<h3>Given :-</h3>
- Pranav ran 20.3 km more than Branda
To find :
- No. of kilometers did Brenda run.
<h3>Let :</h3>
- No. of kilometers ran by Brenda be x.
<h3>Solution:</h3>
Equation formed:-
Total distance covered by Pravan = More distance covered by Pravan + distance covered by Brenda.
Therefore:-
Write the equation
When we transfer 20.3 to left side the positive sign (+) will change into negative sign (–)
Arrange the equation because x is always represented at left side.
After subtracting 38.6 with 20.3 we will get result as 18.3 .
X=28
It is simple just do percentases and then all the outside stuff
Answer:
2x + 3 )(x + 2 )
Step-by-step explanation:
2x² + 7x + 6
Find two numbers multiplied together to get 6
and if you multiply one by 2, the answer is 7:
Tested:
6 & 1 but 6 · 2 + 1 = 13 or 6 + 2 · 1 = 8 No
2 & 3 and 2 · 2 + 3 = 7 Yes
2x² = 2x & x
all signs are positive
trinomial factoring ( )( )
( + )( + )
2 and 3 are the numbers to use (2x + 3 )(x + 2 ) or (2x + 2) (x + 3)
The largest number goes with the 2x.
Therefore (2x + 3 )(x + 2 )
Check 2x(x + 2) + 3(x + 2)
2x² + 4x + 3x + 6
2x² + 7x + 6 checked
