Answer:
The two numbers are -5 and -4
Explanation:
Assume that the first number is x and that the second number is x+1.
We know that the sum of their squares is 41. This means that:
x² + (x+1)² = 41
We will expand the brackets and factorize to get the value of x as follows:
x² + (x+1)² = 41
x² + x² + 2x + 1 = 41
2x² + 2x + 1 - 41 = 0
2x² + 2x - 40 = 0
We can divide all terms by 2 to simplify the equation:
x² + x - 20 = 0 ..........> equation required in part II
Now, we can factorize this equation to get the values of x:
x² + x - 20 = 0
(x-4)(x+5) = 0
either x = 4 .........> rejected because we know that x should be negative
or x = -5 ...........> accepted
Based on the above calculations, the two numbers are -5 and -4
Hope this helps :)

Answer:
There are 500 students which attends McCord Middle School.
Step-by-step explanation:
Given:
Number of students rode their bike or walked to school =200
percent of students rode their bike or walked to school = 40%
We need to find the total students attend the school.
Solution:
Let the number of total students attending the school be 'x'.
So we can say that;
percent of students rode their bike or walked to school multiplied by total students attending the school is equal to Number of students rode their bike or walked to school.
framing in equation form we get;

Dividing both side by 0.4 we get;

Hence There are 500 students which attends McCord Middle School.
