Answer:
I will tomorrow :)
Step-by-step explanation:
D. 15 m, 2m, 2.5m. it doesn’t match the triangle inequality theorem. the sum of the side lengths don’t exceed that of the third side
Lets say w is the width of the flower bed. We can make an equation to find the area.
The length of the of the flower bed is (w+5) and the width is w.
To find the area we need to multiply the length(w+5) by the width(w) and set it equal to 84,
(w+5)(w)=84
w^2 +5w=84
Using the quadratic equation you get the solutions of 7 and -12. Since 7 is positive it is our width. Our length is 7+5 or 12.
Answer:
(X , Y) = (3 , -2)
Step-by-step explanation:
Assuming this is solved via the comparison method ...
<em>-5/3x+3 = 1/3x-3</em> which gets you x = 3
Now, substitute the given value of x into the equation, y=1/3x-3(-3)
Solve for Y, Y=-2
<em>The possible solution of the system is the ordered pair (X , Y)</em>
<em>(3 , -2)</em>
