The smallest of two integers is 61
Step-by-step explanation:
Let x be the smaller integer
Then the next integer will be:
x+1
According to given statement that the sum of both is 123
Subtracting 1 from both sides
Dividing both sides by 2
The smallest of two integers is 61

x(x) = x²
x(9) = 9x
-2(x) = -2x
-2(9) = -18
x² + 9x - 2x - 18
simplify by combining like terms
x² + 9x - 2x - 18
x² + 7x - 18
x² + 7x - 18 is your answer
hope this helps

Answer:
The correct answer is option C. x² - 4
Step-by-step explanation:
Area of rectangle = Length * Width
It is given that ,
The length of a side of a rectangle is 2 units less than a number, and the width is 4 units more than the length.
Let 'x' be the number
Length of rectangle = x - 2
Width = Length + 4 = x - 2 + 4 = x + 2
<u>To find the area of rectangle</u>
Area = Length * Width
Area = (x - 2)*(x + 2) = x² - 4
Therefore option C. x² - 4 is the correct answer
