Factor using the difference of squares.
a^2-b^2 = (a+b)(a-b)
100n^2-1
(10n+1)(10n-1)
Final answer: (10n+1)(10n-1)
This is quite simple. We will first add the amount of miles walked together.
3.25+5.5=8.75
Then we will divide 175 by the number of miles walked which in this case is 8.75.
Then we get 20 which is the amount of money that his parents donated for every mile that he walked.
- The system of equations has infinite many solutions.
- The y-intercepts of the equations are -8
- The slope for the Rover A equation is 1.9 and slope for the Rover B equation is 1.9
Step-by-step explanation:
Given equations are:
Rover A: y= 1.9x – 8
Rover B: 7y= 13.3x - 56
simplifying the second equation
Dividing both sides by 7
As we can see that both equations are equivalent
Slope-intercept form is :
Comparing both equations with slope-intercept form we get
Slope of Rover A = 1.9
Slope of Rover B = 1.9
y-intercepts = -8
As both equations are equivalent, the system will have infinite many solutions.
Hence,
- The slope for the Rover A equation is 1.9 and slope for the Rover B equation is 1.9
- The y-intercepts of the equations are -8
- The system of equations has infinite many solutions.

The equation to find a hypotenuse is
A^2 + b^2=c^2
Plug in the numbers
30^2 + 40^2 = c^2
900 + 1600 =c^2
2500 = c^2
The square-root of 2500 = c
50=c
The hypotenuse of the triangle is 50
