You didn’t show the graph so i can’t tell what the numbers are so i can’t figure out the slope or y-intercept
Answer:
84 Sq in
Step-by-step explanation:
area of the composite figure = Area of square + Area of triangle
You do the same operation on both sides.
Hope this helps!
Answer:
15
Step-by-step explanation:
Okay so I do this kind of weird so it might be a little confusing
What's easier for me is this.. 125 * 10 is 1250
Now there is 625 left to the problem is 625/125
Then I do 125 + 125 + 125 + 125 + 125 (Adding it 5 times so that I can see when it hits 625 is easier than dividing for me)
So you take the 10 from the first part and the 5 from the second part (Got the 5 because you added it 5 times)
10 + 5 is 15
Answer:
-8
Step-by-step explanation:
For roots r and s, the quadratic can be factored ...
f(x) = (x -r)(x -s) = x^2 -(r+s)x +rs
Then the value of r^2+s^2 can be determined from the coefficient of x (-(r+s)) and the constant (rs) by ...
r^2 +s^2 = (-(r+s))^2 -2(rs) = (r^2 +2rs +s^2) -2rs = r^2 +s^2
Comparing this to your given equation, we have the coefficient of x as (-2m) and the constant term as (m^2+2m+3). Forming the expression ...
(x-coefficient)^2 -2(constant term)
we get ...
r^2 +s^2 = (-2m)^2 -2(m^2 +2m +3) = 2m^2 -4m -6
r^2 +s^2 = 2(m -1)^2 -8
The minimum value of this quadratic expression is where m=1 and the squared term is zero. That minimum value is -8.
