Answer:
c = 1
Step-by-step explanation:
Given
x² + 2x + c
To complete the square
add ( half the coefficient of the x- term )² to x² + 2x
x² + 2(1)x + 1
= (x + 1)²
Thus
x² + 2x + 1 = (x + 1)² ← a perfect square
with c = 1
The value of the expression will be 8.166.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The mathematical expression is,
⇒ 13.41 x (5.4 divided by 9)
Now,
Solve the expression as;
⇒ 13.41 x (5.4 divided by 9)
⇒ 13.41 x (5.4 ÷ 9)
⇒ 13.41 x 0.6
⇒ 8.166
Thus, The value of the expression will be 8.166.
